Book Synopsis The Effects of Angularity on the Compaction and Shear Strength of a Cohesionless Material by : Richard Edward Swiderski
Download or read book The Effects of Angularity on the Compaction and Shear Strength of a Cohesionless Material written by Richard Edward Swiderski and published by . This book was released on 1976 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: Several physical methods are described for the practical measurement and rating of angularity (shape) of cohesionless soil particles. Angularity is determined by utilizing the fundamental property of a sphere: a sphere has the smallest contact surface area of any shape for a given volume. Therefore, any other shape will exhibit a greater contact surface area and consequently will have a greater frictional resistance which is a function of its degree of angularity. The effects of angularity on the physical behavior (e.g. strength) of cohesionless soils was investigated at various relative compaction densities. For this purpose a combined compaction and direct shear test device constructed from a modified standard Proctor compaction mold was devised. The samples used to determine the effect of particle shape on the physical behavior of cohesionless materials were produced in the lab from pure quartz. This was done in order to avoid the problem of variations due to mineral composition and grain size distributions. It was hoped that this would insure a greater uniformity of test results. In addition, the shear test results derived from lab-produced quartz samples were compared to those of natural field samples in order to determine whether the behavior observed during lab tests was representative of natural field soils. These experiments demonstrated that the strength of a cohesionless material increases with degree of angularity and relative density to an optimum point. Surpassing the optimum value implies substantial particle crushing which reduces the particle interlocking effect and can result in a reduction of soil strength. Crushing is greatest when cohesionless particles are poorly graded, highly angular, and large in size. Generally, the degree of particle crushing influences strength, and particle shape determines the degree of crushing. Shape (angularity), therefore, significantly controls the overall strength of a cohesionless soil.

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.

Book Synopsis Effects of End Conditions on Triaxial Compressive Strength for Cohesionless Soil by : S. Goto
Download or read book Effects of End Conditions on Triaxial Compressive Strength for Cohesionless Soil written by S. Goto and published by . This book was released on 1988 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: Drained triaxial compression tests of Toyoura sand were carried out with conventional triaxial apparatus to evaluate the effects of sample slenderness and end conditions on triaxial compression strength. It was found that the maximum difference in the angle of internal friction ?d for different test conditions employed was about ±1°. At the same time, the effects of the sample slenderness and each end condition on the strength value could be clearly identified.

This book was released on 1975 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: The results of a series of consolidated-undrained (CU) triaxial compression tests performed on normally consolidated and overconsolidated specimes of two clays consolidated both isotropically (ICU tests) and anisotropically (ACU tests) are presented and analyzed in this report. The specimens were trimmed from samples of Vicksburg Buckshot clay (LL = 57) and a clay from the East Atchafalaya Basin Protection Levee (EABPL) project area (LL = 79), both of which had been consolidated from a slurry in large-diameter consolidometers under a maximum vertical consolidation pressure of 3.0 kg/sq cm. Data presented include stress-strain curves, pore pressure observations, final water content distributions within the specimens, and shear strength envelopes based on total and effective stresses. Test results indicate that the change in volume during consolidation and the water content at the end of consolidation are not a unique function of the vertical consolidation stresses but are related to the mean effective consolidation stress. Total stress envelopes based on Taylor's method of deriving strengths of anisotropically consolidated specimens from test results obtained from isotropically consolidated specimens slightly underestimate observed values. In this context, Taylor's method is an appropriate means of predicting strengths for various K sub c ratios from conventional ICU tests. Use of hyperbolic stress-strain relationships derived from ICU tests in finite element codes for ACU conditions will lead to erroneous results. Further testing of anisotropically consolidated soils under stress systems that better simulate in situ conditions is needed.
