THEORIES WITH DISCUSSION

The symposium on laboratory shear testing of soils, sponsored by ASTM Committee D-18 on Soils for Engineering Purposes and the National Research Council of Canada, was held in four sessions from September 9 to 11, 1963, in Ottawa, Canada. The author summaried the papers presented at the first session of the symposium. He contends that theories of shear strength occupy an important place on soil mechanics. They have to satisfy two main requirements: (1) the theories should describe the shear strength relationships of soils by means of fundamental strength parameters (analytical requirement); (2) these parameters should be directly applicable to strength and stability problems, such as earth pressures, stability of slopes, and bearing capacity of foundations (design requirements). Unfortunately, it is difficult to satisfy both the analytical and design requirements at the same time. The Coulomb-Mohr theory and others are explored in seven papers divided into two sections, the first concerns significant limitations of the Coulomb-Mohr theory and the second section deals with some important factors influencing the components of shear-strength parameters. Discussion follows the Meyerhof's review of the articles.
