主应力轴旋转情况下土的各向异性研究进展
Study Development of Soil's Anisotropy under Principal Stress Rotation
摘要
Abstract
From two aspects of theory and experimen, research on soil's anisotropy under principal stress rotation in home and abroad are compared and summarized, also some research suggestions are proposed. It is pointed out that in theory, the three-dimensional description for the yield surface of constitutive model, whose yield surface equation is expressed by stress components, should be well studied, and the change characteristics of yield surface under different load directions as well as rotational hardening should be taken into account. In experiment, the experimental subject should better be clay, and along with the theoretical research, the experimental study on the change characteristics of yield surfaces under different load directions and verification of the rotational hardening is worth looking into.关键词
