Available in PDF, EPUB and Kindle. Book excerpt: Considering the difficulties associated with preparing loose sand samples in large calibration chambers and wide area of research on the behavior of loose sands, miniature calibration chamber experiments are used to perform cone penetration tests on soils in different states. A miniature cone calibration chamber has been designed and developed in this study. Nineteen tests have been performed on Ottawa sand and the results are compared to the available data in the literature. The accuracy of the results is validated by comparing the results with the suggested rate for the cone resistance in sands in literature. More specifically, results are compared with the results of the large calibration chamber tests performed on the same soil at University of Florida. Results are in a very good agreement with the literature and data available from large calibration chambers. Different soil identification systems are used to further validate and compare the results. Results of the performed tests are presented and discussed in terms of the repeatability of the developed apparatus, the effect of penetration rate, boundary condition effect, scale effect, particle crushing, overburden stress normalization and verification of the measurements. Some available procedures to perform a CPT-based liquefaction analysis including liquefaction susceptibility, triggering and post-liquefaction strength analysis are evaluated using the laboratory miniature CPT experiments performed in the current study. Some of the well-stablished equations to estimate soil properties required for liquefaction studies are also evaluated using the laboratory miniature CPT experiments performed in the current study. The existing methods for estimating state parameter from cone penetration test results are reviewed and an evaluation of the performance of the existing methods using the laboratory miniature CPT experiments performed in the current study is presented.

This book was released on 2006 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The static cone penetration tests are quite extensively used for carrying out in-situ geotechnical investigations both for onshore and offshore sites especially where the soil mass is expected to comprise of either soft to medium stiff clays or loose to medium dense sands. The wide use of the cone penetration tests (CPT) in geotechnical engineering has resulted in a great demand for developing necessary correlations between the cone penetration resistance and different engineering properties of soils. The successful interpretation of the cone penetration test data depends mainly on the various empirical correlations which are often derived with the help of a controlled testing in calibration chambers. The calibration chambers have been deployed in various sizes (diameter varying from 0.55 m to 2.10 m) by a number of researchers. It is quite an expensive and time consuming exercise to carry out controlled tests in a large size calibration chamber. The task becomes even much more difficult when a sample comprising of either silt or clay has to be prepared. As a result, most of the reported cone penetration tests in calibration chambers are mainly performed in a sandy material. Taking into account the various difficulties associated with performing tests in large calibration chambers, in the present study, it is attempted to make use of a miniature static cone penetrometer having a diameter of 19.5 mm. This cone was gradually penetrated at a uniform rate in a triaxial cell in which a soil sample of a given material was prepared; the diameter of the cone was intentionally chosen smaller so that the ratio of the diameter of the cell to that of the cone becomes a little larger. Two different diameters of the cells, namely, 91 mm and 140 mm, were used to explore the effect of the ratio of chamber (cell) size to that of the cone size. In addition, the rate of penetration rate was also varied from 0.6 mm/minute to 6.0 mm/minute (the maximum possible rate for the chosen triax.

Book Synopsis Correlations of Soil and Rock Properties in Geotechnical Engineering by : Jay Ameratunga
Download or read book Correlations of Soil and Rock Properties in Geotechnical Engineering written by Jay Ameratunga and published by Springer. This book was released on 2015-12-11 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a one-stop reference to the empirical correlations used extensively in geotechnical engineering. Empirical correlations play a key role in geotechnical engineering designs and analysis. Laboratory and in situ testing of soils can add significant cost to a civil engineering project. By using appropriate empirical correlations, it is possible to derive many design parameters, thus limiting our reliance on these soil tests. The authors have decades of experience in geotechnical engineering, as professional engineers or researchers. The objective of this book is to present a critical evaluation of a wide range of empirical correlations reported in the literature, along with typical values of soil parameters, in the light of their experience and knowledge. This book will be a one-stop-shop for the practising professionals, geotechnical researchers and academics looking for specific correlations for estimating certain geotechnical parameters. The empirical correlations in the forms of equations and charts and typical values are collated from extensive literature review, and from the authors' database.

This book was released on 2015 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cone penetration testing (CPT) has become the industry standard for in situ testing of cohesionless soils, and in particular, field liquefaction evaluation. The empirical methods for the interpretation of CPT data are either based on field data or the observation of CPT measurements in laboratory samples. In this study, a miniature cone penetrometer (with a diameter of 6 mm) is developed for understanding the response of loose to medium-dense sands. A modified triaxial cell is used for sample preparation and containment of the sample during cone penetration. The miniature cone can measure cone tip resistance, sleeve friction, and excess pore water pressure developed at the cone tip. While cone tip resistance is measured by a separate load cell, sleeve friction is obtained by subtracting cone tip resistance from a combined measurement of tip resistance and sleeve frictional force. Due to the free-draining nature of the sand tested in this study, no excess pore water pressure is developed during cone penetration. The measured data from the miniature cone are verified by comparison with CPT resistances measured in several other calibration chamber experiments on similar sands. Compared to a large calibration chamber with a standard size cone, the miniature cone allows quicker and less expensive CPT experiments in a more uniform sample.

Book Synopsis Cone Penetration of Partially Saturated Sands by : RD. Hryciw
Download or read book Cone Penetration of Partially Saturated Sands written by RD. Hryciw and published by . This book was released on 1987 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: A laboratory study of cone penetration through partially saturated sand was conducted. A new method for preparing specimens at various degrees of saturation, which utilizes pressure release from previously carbonated water, is described. In closed water systems, where capillary tensions increase effective confining pressures, penetration resistance was significantly higher than in either dry or saturated conditions. Conversely, in closed-gas systems the penetration resistance was slightly lower than at full saturation.

Book Synopsis Evaluation of Cone Penetrometer Testing to Determine in Situ State of Sands by : Geoffrey R. Martin

This book was released on 1980 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "Verification of the densities for artificial sand fill islands in the Beaufort Sea is currently carried out using the cone penetration test (CPT). Cone penetration resistance is converted to relative density using one of the correlations published by Baldi et al (1982), Villet and Mitchell (1981) or Schmertmann (1975). These correlations have been derived on the basis of prototype chamber CPT tests on clean, generally dense, sands. Sand fills in the Beaufort Sea contain nominal silt fractions (1-5% fines) and the densities of interest are frequently less than those reported in the CPT chamber test programs. There is no sound justification that these published correlations in terms of relative density are valid for evaluation of sand fills in the Beaufort Sea. Ideally, a correlation between cone resistance and density would be developed for each sand type used in island construction. Such a program of CPT chamber tests would be extremely costly and time consuming. Early in 1984, Golder Associates proposed an alternative approach to CPT interpretation to Dome Petroleum, based on the state parameter approach to sand behaviour. It was hypothesized that the cone penetration resistance could be uniquely related to the state parameter, and that this correlation may be equally applicable to clean and silty sands. The initial phase of the evaluation of the state parameter approach to CPT interpretation involved a reinterpretation of existing calibration chamber test data in terms of state parameter. In order to do this, the Steady State line for each of the relevant CPT calibration sands must be known. The findings of the initial evaluation of the CPT/state interpretation are contained in this report.... One of the objectives of this study was to determine which correlation, if any, is most applicable to silty Beaufort Sea sand fills. On the basis of laboratory testing data, the CPT correlation sands essentially show the same engineering behaviour at large (failure) strains as Beaufort Sea sands, with or without silt. On this basis, any of the correlations with state parameter are applicable and the data on Figure 13 could readily be used to determine in situ state from CPT tests with reasonable accuracy. The significant point of the study is that a state parameter approach to CPT interpretation provides a rational interpretation of cone resistance in silty sands. Many of the problems associated with interpretation in terms of relation density along are avoided using the state parameter approach"--ASTIS database.

Book Synopsis Correlation Between Miniature Cone Tip Resistance and Shear Strength Parameters of Clean and Silty Sand Using a Conventional Triaxial Setup by : Jyant Kumar
Download or read book Correlation Between Miniature Cone Tip Resistance and Shear Strength Parameters of Clean and Silty Sand Using a Conventional Triaxial Setup written by Jyant Kumar and published by . This book was released on 2008 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ultimate tip resistance of the cone was determined by employing a miniature cone penetrometer of diameter 19.5 mm in conventional triaxial equipment. A number of penetration tests were carried out for clean and silty sands. The variation of the tip resistance was determined with respect to changes in effective vertical stress (?v). It was seen that with this laboratory experimental setup, it is possible to make a reasonable prediction of the ultimate cone tip resistance (qcu). As expected, the tip resistance increases with an increase in (?v). For the same range of the relative density, an increase in proportion of silt was found to generally cause a reduction in the tip resistance. By considering the effect of the overburden stress on internal friction angle of soil mass, it was noted that the magnitude of qcu/?v increases almost linearly with friction angle. The obtained values of qcu compare reasonably well with two different widely used correlations in literature. It is expected that the study will be useful for deriving correlations between shear strength parameters and the cone tip resistance for cohesionless deposits at different values of the effective overburden pressure especially for loose to medium dense states.
