摘要
本文通过对某地下厂房周围的变质岩岩体特征的研究,发现该岩体的断裂构造发育的优势方向同岩体片理方向是一致的,而且岩体在片理的两个正交方向表现出不同的力学特性,本文将其归纳为正交异性岩体,并在此基础上对地下厂房开挖后围岩稳定性问题进行了有限元初步分析。
Through the studies of fractures of surrounding rock mass and its mechanical properties, the transversely anisotropic model of rock mass is established. In the end, the periphery deformation, stress redistribution and relaxed zones of surrounding rock mass are given by means of finite element analysis, meanwhile the stability of surrounding rock mass is evaluated.
