Finite Element Simulating Computation for Joint Rock Based on Composite Constitutive Models

摘要: 从代表元方法出发，建立节理岩体的本构方程，进行有限元仿真分析，计及了节理宽度、刚度及走向等对岩体结构力学特性的影响

Abstract: Starting from representative element, constitutive models of joint rock are established. A finite element simulating procedure is employed to analyze the effect of joint on whole structure, with the width, stiffness, and strike of joint being taken into account.
