Book Description
Shear strength of soils is an important engineering aspect because shear strength characteristics are widely used in various applications such as bearing capacity and earth pressure of soils. Shear strength of sands is somewhat simpler than that of clays, which are complex materials exhibiting engineering behaviour difficult to predict. Shear strength of clays depends of water content, drainage conditions, rate of loading and degree of compaction.Unconfined compression tests were performed on cylindrical samples compacted at different remoulded densities chosen from the compaction curves of the soil. Proctor compaction tests were performed on the soil at three different compaction energies corresponding to N=25, 35 and 50. Dry densities of test samples corresponding to water contents of 10%,12% and 14% were chosen from the three compaction curves pertaining to N=25,35 and 50. Remoulded cylindrical samples were prepared for the performance of unconfined compression tests at the above dry densities and water contents. Stress strain characteristics, variation of peak compressive stress with significant parameters were studied.

Book Description
Highway embankment is one of the most common large-scale geotechnical facilities constructed in Ohio. In the past, the design of these embankments was largely based on soil shear strength properties that had been estimated from previously published empirical correlations and/or crude soil test results. This is because either the actual soil fill material is not available for testing at the time of embankment design or detailed shear strength determination of soil samples in the laboratory tends to be time-consuming and expensive. Structural stability of these embankments is vital to the state economy and public safety. There is a strong need to conduct a study to examine whether the empirical correlations are truly applicable to Ohio soils and to develop comprehensive geotechnical guidelines concerning the shear strength properties of cohesive soils typically used in Ohio. In this study, soil samples from nine highway embankment sites scattered across Ohio were tested both in the field and laboratory to establish comprehensive geotechnical properties of cohesive soil fills, which represent a wide range of geological features existing in the state. The large volume of soil data produced in the study was then analyzed to evaluate reliability of the empirical correlations and derive statistically strong correlations for shear strength properties of cohesive soil fill materials found in Ohio. Based on the outcome of these analyses, multi-level guidelines are proposed by the author for estimating shear strength properties of Ohio cohesive soils more confidently.

Book Description
This book is the international edition of the proceedings of IS-Seoul 2011, the Fifth International Symposium on Deformation Characteristics of Geomaterials, held in Seoul, South Korea, in September 2011.The book includes 7 invited lectures, as well as 158 technical papers selected from the 182 submitted. The symposium explored ideas about the complex load-deformation response in geomaterials, including laboratory methods for small and large strains; anisotropy and localization; time-dependent responses in soils; characteristics of treated, unsaturated, and natural geomaterials; applications in field methods; evaluation of field performance in geotechnical structures; and physical and numerical modeling in geomechanics. These topics were grouped under a number of main themes, including experimental investigations from very small strains to beyond failure; behavior, characterization and modeling of various geomaterials; and practical prediction and interpretation of ground response: field observation and case histories. Both the symposium and this book represent an important contribution to the exchange of advanced knowledge and ideas in geotechnical engineering and promote partnership among participants worldwide.

Book Description
During the 1973 Annual Meeting of the Transportation Research Board (formerly Highway Research Board) participants in a symposium on shear strength of fine- grained soils during construction discussed the measurement of field strength and other indicative parameters, and how best to use these data to control construction. Four papers presented during this symposium and two additional papers on related subjects, have been published in this issue of the record.
