摘要：节理岩体的受力性能既取决于材料本身,又取决于节理面的力学性能.特别是剪切引起的节理面塑性性能对节理乃至整个岩体的力学反应都会有一定的影响.采用有限元方法并利用考虑节理塑性的弹塑性节理单元仿真裂缝,探讨了节理面塑性对节理体弹性性能的宏观影响.%Properties of the jointed rock mass depend not only on the material itself but also on the behaviour of the joints. The shearing induced plastic behaviour of a joint has certain impact on the mechanical response of the joint and on the jointed rock mass. This paper investigates the influence on the damage elasticity of the jointed mass due to the plasticity in joints. The analysis is based on a numerical model using an elasto-plastic joint element to simulate the discontinuities.
