Download or read book Multistage Triaxial Testing of Lightly Overconsolidated Clays written by RHG Parry and published by . This book was released on 1973 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: A comparison has been made between consolidated undrained tests on separate soil specimens and multistage testing of a single specimen. Three series of samples were prepared, two of the series consisting of remolded kaolin in each of which the specimens were lightly overconsolidated under K0 conditions, and one series consisting of undisturbed specimens of soft silty clay from a site at Fulford near York in England. It is concluded from these tests that although some differences arise from the two methods, the results from multistage tests are adequate for practical purposes both in the prediction of failure conditions and in the prediction of deformations and pore pressure response under working loads. In view of the number of advantages accruing from multistage testing, it is recommended that this method should be used in the routine triaxial testing of soft lightly overconsolidated clays of low sensitivity.

Available in PDF, EPUB and Kindle. Book excerpt: Natural soft soils are very complex materials. As construction activities increasingly take place in poor ground conditions, ground improvement is often required. However, design practices for ground improvement were for long at best crude and conservative, and at worst unsafe. Although new construction and field observation techniques have been de

Download or read book Triaxial Tests for Typical Winnipeg Clays written by Nalin Princy Samarasingha and published by . This book was released on 1966 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Presented in this thesis are the results of a series of Triaxial tests run on undisturbed samples of a highly plastic Winnipeg clay. The shear strength properties, pore pressure characteristics and the effect of the strain rate were investigated and compared with the available information. The results indicate the presence of a low angle of shearing resistance and a high cohesion intercept. The nature of the pore pressure change due to applied deviator stress indicates Winnipeg clays as being lightly over-consolidated. The rate of strain is seen to influence the test results in the consolidated undrained tests. For reliable results in such a test a strain rate with a time to failure of four to six hours or more appears satisfactory.

Available in PDF, EPUB and Kindle. Book excerpt: A technique to predict the stress-strain behavior of clays along various stress paths is presented. The experimental results of stress-controlled triaxial pure shear and consolidation tests conducted on normally consolidated and lightly overconsolidated samples are given, and a method to evaluate the parameters required for prediction by the proposed technique is discussed. Comparison between experimental and predicted stress-strain behavior of normally consolidated and lightly overconsolidated samples along stress paths shows that the technique predicts the behavior quite well.

Available in PDF, EPUB and Kindle. Book excerpt: "Although the triaxial compression test is presently the most widely used procedure for determining strength and stress-deformation properties of soils, there have been no books published on triaxial testing since the 1962 second edition of the landmark work The Measurement of Soil Properties in the Triaxial Test by Bishop and Henkel. It is apparent there is a need to document advances made in triaxial testing since publication of Bishop and Henkel's book and to examine the current state of the art in a forum devoted solely to triaxial testing. Because of increasing versatility brought about by recent developments in testing techniques and equipment, it is also important that the geotechnical profession be provided with an up-to-date awareness of potential uses for the triaxial test."--Overview.
Download or read book Deformation and Progressive Failure in Geomechanics written by A. Asaoka and published by Elsevier. This book was released on 1997-10-23 with total page 956 pages. Available in PDF, EPUB and Kindle. Book excerpt: Progressive failure has been a classical problem in the field of geotechnical engineering and has attracted considerable attention in connection with slope stability and foundation problems. It is associated with strain localization or shear banding and is also related to damage in material structures. As knowledge of the progressive failure mechanism increases, it is now necessary to establish effective communications between researchers and engineers. The International Symposium on Deformation and Progressive Failure in Geomechanics provided an opportunity for discussing recent advances in this area. A total of 136 papers were contributed from 22 countries. As well as these, the symposium proceedings also contain 8 interim technical reports on the subject by the members of the Asian Technical Committee of the International Society for Soil Mechanics and Foundation Engineering and the Japanese Geotechnical Society National Committee on Progressive Failure in Geo-structures.

Download or read book Multistage Triaxial Testing to Estimate Effective Stress Relationships for Unsaturated Compacted Soils written by Ali Khosravi and published by . This book was released on 2012 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper presents an experimental methodology for using multistage, drained triaxial tests on compacted soils under unsaturated conditions to estimate soil-specific relationships between mean effective stress and matric suction. Tests were performed by applying a matric suction to a soil specimen in a triaxial cell using the axis translation technique with back-pressure, then shearing the specimen under drained conditions until reaching stress-path tangency. The specimen was then unloaded, a new suction was applied, and the shearing process was repeated. The points of maximum principal stress difference for the unsaturated specimen were plotted versus mean effective stress, defined using the degree of saturation as the effective stress parameter, and they were found to correspond well with the critical state line defined from triaxial tests on saturated specimens. The suction stress for the compacted soil tested in this study was observed to increase nonlinearly with suction, tending toward a constant value with increasing suction. Although there are potential changes in soil structure in the specimen during loading, unloading, and reloading, the results indicate that the multistage testing method may be useful for estimating soil-specific effective stress parameters for compacted soils in unsaturated conditions. Furthermore, the fact that differences in the soil-water retention curve of soil specimens subjected to different net confining pressures were observed for the soil tested in this study emphasizes the importance of using soil-specific tests to validate predictive relationships between suction stress and matric suction.
