The objectives of this investigation were to develop a rotation shear machine to measure the residual shear strength (constant shearing resistance at which material undergoes continuous deformation under a constant state of effective stress) of clays and clay-shales; investigate testing errors; and measure residual shear strengths of representative types of highly plastic clays and clay-shales. In the rotation shear test, torque is applied to the bottom of the specimen and two force transducers measure the couple necessary to maintain the upper half of the specimen stationary. Disc-shaped or annular specimens with thicknesses from 0.1 to 2.5 cm and outside diameters of 7.11 cm can be tested. Variations in residual shear strength were investigated for normally consolidated versus overconsolidated specimens, for specimens sheared at different rates of peripheral displacement, and for specimens prepared by several different remolding procedures.

This book provides a comprehensive text on the geotechnical and geological aspects of the investigations for and the design and construction of new dams and the review and assessment of existing dams. The book provides dam engineers and geologists with a practical approach, and gives university students an insight into the subject of dam engineering. All phases of investigation, design and construction are covered, through to the preliminary and detailed design phases and ultimately the construction phase. This revised and expanded 2nd edition includes a lengthy new chapter on the assessment of the likelihood of failure of dams by internal erosion and piping.

Every engineering structure, whether it's a building, bridge or road, is affected by the ground on which it is built. Geology is of fundamental importance when deciding on the location and design of all engineering works, and it is essential that engineers have a basic knowledge of the subject. Engineering Geology introduces the fundamentals of the discipline and ensures that engineers have a clear understanding of the processes at work, and how they will impact on what is to be built. Core areas such as stratigraphy, rock types, structures and geological processes are explained, and put in context. The basics of soil mechanics and the links between groundwater conditions and underlying geology are introduced. As well as the theoretical knowledge necessary, Professor Bell introduces the techniques that engineers will need to learn about and understand the geological conditions in which they intend to build. Site investigation techniques are detailed, and the risks and risk avoidance methods for dealing with different conditions are explained. - Accessible introduction to geology for engineers - Key points illustrated with diagrams and photographs - Teaches the impact of geology on the planning and design of structures
