This book was released on 1988 with total page 141 pages. Available in PDF, EPUB and Kindle. Book excerpt: The research study undertaken at Purdue focuses towards increasing our understanding of fundamental issues related to the behavior of clays, especially with regard to modelling their anisotropy. The information being developed is applicable to most geotechnical problems, however, in illustrating their usefulness, emphasis is placed on interpretation of in situ tests, and in particular pressuremeter and self-boring pressuremeter (SBPM) tests. There is ample evidence that in situ soils are anisotropic, elasto-plastic, stress path and rate dependent, unlike what is generally assumed in test interpretations. Therefore, the study of mechanisms of deformation of in situ tests and their interpretation must take into account these features, and especially the anisotropic nature of the soil deposit. A simple and reliable anisotropic theory will be most useful in the study of several important factors related to pressuremeter testing such as possibility of radial cracking, role of vertical stress, stress conditions at failure, and the effects of initial disturbance which cannot be measured. It will also be possible to estimate undrained strength of the clay in other modes of failure using SBPM data only. (kr).

Available in PDF, EPUB and Kindle. Book excerpt: This research was undertaken to answer issues related to cavity expansion and in-situ testing using the pressuremeter. Emphasis of the research was placed upon validating the fundamental concepts underlying the cylindrical cavity expansion theory. Test were performed in a cuboidal shear device (CSD) at strain rates of 0.01%, 0.05%, 0.10%, 0.50%, 1.00% and 5.00% per minute on artificially sedimented specimens of kaolin clay and a kaolin-ground silica mixture with a plasticity index in the range similar to most clays. It was found from the experiments that the normalized shear strength (with respect to 0.01%/min) increases linearly with the logarithm of strain rate. The increase in undrained shear strength in the pressuremeter stress path is about 14.3% per log cycle for kaolin clay and 15-3% for the kaolin-silica mixture. The undrained shear strength in the conventional triaxial test was found to increase about 8 to 10% for a tenfold increase in strain rate. Therefore, it can be concluded that the undrained shear strength increases about 40-50% more in pressuremeter stress path tests than in the triaxial stress path tests. A new state variable, indicative of the fabric of clays is introduced. Based on these concepts and a general failure criterion, a simple model to predict failure parameters of anisotropic clays for many commonly encountered stress paths was developed. The model capability to interpret in situ strength measured under a given stress path and transfer it to another stress path was illustrated. Finally, the ability to obtain failure parameters for any stress path using data from a single CIUC test was demonstrated.

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.
