| 摘 要： | 本文提出了一种确定节理岩体力学参数的计算机模拟试验法。该法基于节理裂隙的野外勘探资料建立岩体的损伤断裂模型,可在计算机上模拟计算实际试验过程,获得应力-应变全过程曲线和岩体变形模量、抗剪强度参数的各自异性特征。文中具体研究了拉西瓦工程岩体参数的取值问题。

| Abstract: | A computer simulation method to predict the mechanical properties of jointed rock mass is pre-sented. Starting from the development of a damage-fracture model for jointed rock mass on the basis of the geological investigation of rock joints, the process of in-situ rock mechanical tests is simulated numerically on the computer by using the proposed model. As a result, the anisotropic values of modulus of deformation and shear strength of rock mass are derived from the obtained complete stress-strain curves. Taking as an example, the prediction of mechanical properties for the jointed rock mass of Lax-iwa hydro-power project is described in detail. |
