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.

This book was released on 1978 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: This investigation examines effects of anisotropic versus isotropic consolidation in consolidated-undrained triaxial compression tests performed on specimens of two clays consolidated from a slurry in large-diameter consolidometers. Shear strength and corresponding deformation characteristics were developed in both normally consolidated and overconsolidated ranges. Test results indicate that volume changes during consolidation are not a unique function of the major principal consolidation stress but instead are related to the mean effective consolidation stress and the deviator stress during consolidation. Consequently, for a given major principal consolidation stress, the undrained strength of anisotropically consolidated specimens is lower than that of isotropically consolidated specimens.

Book Synopsis Behavior of a Remolded Silty-clay Subjected to Sequential Loading by : Lawrence Tsi-Ching Chung

This book was released on 1970 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The investigation was undertaken to determine shear strength and pore pressure parameters of a soil when subjected to sequential loading. This method is intended to similate the in-situ condition of stress application under certain field conditions. The testing procedure, a sequential triaxial shear test, is described. This test consists of successive stages of partial consolidation followed by undrained shear. Triaxial consolidation and shear strength characteristics of a sedimented remolded silty-clay are compared with the results from conventional tests on isotropically consolidated samples. The undrained strength was found to be a function of moisture content, irrespective of the method of test and initial stress system for the normally consolidated soil. A unique relationship was established between a pore pressure parameter, the ratio of the change in pore pressure to the effective vertical consolidation pressure, and undrained strength. It is concluded that this sequential procedure of testing does change the strength characteristics of the soil. These cannot be predicted from the conventional test"--Abstract, page ii.

Available in PDF, EPUB and Kindle. Book excerpt: The laboratory procedure most commonly used for strength determination is the triaxial compression test. The relationship between data obtained with this test procedure and the in-situ strength of a soil under comparable deformation conditions (i.e., axially symmetric strain and same orientation of principal stresses) will be the subject of this report.

Book Synopsis Interrelationship Between Undrained Shear Strength from DMT and CPTU Tests for Soils of Different Origin by : Zbigniew Mlynarek

This book was released on 2018 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: The article presents test results on the use of the flat dilatometer test (DMT) to evaluate changes in undrained shear strength su in soils of various origins. Reference values for the undrained shear strength calculated with Marchetti's original formula were su values obtained from the piezocone penetration tests. The tests were conducted at eight investigation sites in Poland, where five groups of soils were separated: loess-deluvial, loess-deluvial cemented, young till, aged till, and Pliocene clay. The soils exhibited varied overconsolidation effects. The study results revealed that the factors influencing the relationship between undrained shear strength and the KD coefficient from DMT test were various because of the origin, grain size distribution of the soils and cementation. In order to include the influence of overconsolidation and grain size distribution in calibration of su from DMT, a modified KD1 coefficient was introduced into the formula describing this relationship. The final solution was obtained with multiple linear regression. A relatively high statistical evaluation of this relationship was determined for aged till and deluvial and uncemented loess.

Book Synopsis Offshore Site Investigation and Foundation Behaviour by : D.A. Ardus
Download or read book Offshore Site Investigation and Foundation Behaviour written by D.A. Ardus and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 769 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two main areas of offshore activity are addressed in this book: Site investigation on assessment; and Applications and foundation engineering. The 37 contributions from a wide ranging group of international experts, are resulting from the Offshore Site Investigation and Foundation Behaviour Conference, London, U.K., September 1992. Adequate determination of site conditions can only be achieved by the integrated approach of using geological, geophysical and geotechnical data. Developments in data acquisition techniques are illustrated through case histories in the section on Geotechnical Sampling and Testing. In the section on Advanced Interpretation Techniques and Integrated Interpretations the state of the art of these topics is also illustrated by case histories. A review of foundation behaviour is presented in the section on Gravity Foundations, Foundation Performance Monitoring, Piling Research and Design Criteria. These topics are illustrated in the light of field experience and recent research, in particular that involving full-scale tests and monitoring. This book provides many illustrative figures and much pertinent information to exploration and marine geophysicists, petroleum and offshore engineers and for researchers working these fields.
