摘要
根据岩体的力学介质分类和块体理论及赤平投影,结合工程实例,推导了滑动方向的计算公式,研究了裂隙化岩体地下采空区围岩的稳定性分析方法。利用该方法分析了华北某大型地下采空区围岩的稳定性,展示了该模型的实用性。
Based on mechanics media classification and block theory and stereographic projection, a calculation formula of sliding direction was deduced; and an analytical method of stability of surrounding rock of underground stope out area in fissure rock-mass was researched with project example. Stability analysis of surrounding rock for a large underground stope out area in North China's Hebei Province was finished by above-mentioned method.
