摘要
按弹塑性体相似判据和破坏阶段相似判据确立相似常数，模拟山体形态、结构面和岩石物理力学性质、地应力、边界条件和埋设测点，建立三维模型，模拟开挖卸荷过程，监测边坡形态、地应力释放和山体应变，认识到边坡变形的主要因素、变形延时和变形量、变形与应力释放的关系及山体应力应变明显变化的范围．
According to simularity criteria of elastoplastic body and simularity criteria of its damage stage,the simularity constants are determined. By simulating mountain body shape, structural sarface, physico-mechanical properties of rock, ground(initial) stress, boundary conditions and embedded measured points;a 3-dimensional model of jointed rock mass of high-steep slope is established. Through simulating load-off process due to excaration; monitoring slope deformation, ground stress-release and strain of mountain body; the recognitions obtained are as follows: main factors of slope deformation, deformation delay and deformation value, relationship between deformation and stress-release,obvious change scope of stress-strain of the mountain body.
