| Summary: | An understanding of the mechanical properties of unsaturalod soils is crucia for geotechnical entineers worldwide, as well as those conccrned with the interaction of structures with the ground. This book deals principally with the grained clays and silts or soils containing coarser sand and gravel particles but with a significant percentage of fines. The Study of unsaturated soil is a practical subject, linking fundmental science to nature Soils in general are inherently variable and their behaviour is not easy to analyse or predict, and unsaturated soils raise the complexity to a higher level. Even amongst practicing entineers, there is often a lack of awareness of the intricacies of the subject. This book offers a perspective of unsatureafed soils based on recent research and demonstrates how this doveteials with the general discipline of soil mechanics. Following an introduction to the basic soil variables the the phases the phase interactions and the relevance of soil structure an up to date review of laboratory testing techniques is presented this includes suction measurement and control techniques in triaxial cell testing. This is followed by an introduction to stress state variables critical state and theoretical models in unsaturated soils. A detailed description of the thermodynamic principles as applied to multi phase materials under equilibrium conditions follows. Tahese principles are then used to explore and explore and develop a fundamental the oretical basis for analysing unsaturated soils. Soil structure is broken down into its compoment paints to develop equatrions describing the dual stress regime. The critical. State strength and compression characteristiies of unsaturated soils are examined and it is shown how the behaviour may be viewd as a three dimensional model in dimensionless stress volume space. The analysis is then extended to the work input into unsaturated soils and the development of conjugate stress, volumetric and strain incerment variables. These are used to examine the micromechanical behaviour of kaolin specimens subjected to trixial shear strength tests and lead to observations detectable by other means. Unsaturated Soils, a fundamental interpretation of soil behaviour covers a rapidly advancing area of study, research and engineering practice and offers a deeper appreciation of the key characteristics of unsaturated soil. It provides students and researchers witha framework for understanding soil behaviour and demonstrates how to interpret experimental strength and compression data. --Book Jacket. |
