-
摘要: 工程地质中岩体层状介质的力学性质除弹性变形与强度表现为各向异性之外,应力应变关系还表现为非线性。本文介绍了对该问题的全量直接求解方法,无需迭代,方法本身不引起误差。本文方法亦可用于有摩擦接触问题。Abstract: The mechanical properties of laminative rock mass appear to be both nonlinear in constitutive stress-strain rela- tions and anisotropic in elastic deformation and strength.This problem can be solved in total strain plasticity directly by the method presented.No iterative process is required to obtain the real solution.This method also discribes the frictional contact problems which are the special case where the layers between mass blocks tend to be zero.
