Mohr Circles, Stress Paths and Geotechnics
Mohr circles are a powerful and widely used technique for representing stresses and strains in soil and rock, and for converting test data into design parameters, but they have many other uses in solving geotechnical problems. Mohr Circles, Stress Paths and Geotechnics gives a unified presentation of the theory and application of the technique and is the first book devoted to the subject.
The introductory chapters explain how to construct and use Mohr circles to represent and interpret soil and rock strength data and to determine total stress and effective stress parameters. Then the link between Mohr stress circles and stress paths is established, and laboratory tests and field behaviour are discussed. Problem solving using Mohr circles or stress paths for isotropic and anisotropic soils and rocks, soil plasticity and stability is explored, with worked examples including foundations, retaining walls, silo pressures and plastic extrusion. The applications of both stress discontinuities and stress characteristics are described for solving plasticity problems.
