摘要
提出在岩土工程应力-应变分析中建立统一坐标系的建议.在此基础上,系统地介绍了平面问题和空间问题中过某点的倾斜面上的应力确定方法并由此应用于八面体应力的确定;对八面体应力和π平面上的应力的几何和物理力学意义进行了比较说明;介绍了一种推导应力或应变洛德角表达式的简明方法;对各种剪应力的相对大小进行了合理的比较与说明.
A suggestion that the coordinate system of stress and strain analysis in geotechnical engineering should be unified is made. Based on this, the methods to ascertain the stresses acting on the inclined planes in plane and spatial problems are introduced systematically. The analysis methods are applied in ascertaining the stresses acting on the octahedron. The geometric and physical mechanics meaning between stresses acting on octahedron and Pi plane is compared and explained. A concise method to deduce the Lode's angle is presented. The magnitude of different shear stresses is compared and expounded reasonably.
