摘要
结合工程实例,对影响地下洞室围岩稳定的因素进行了研究。将围岩抗剪强度参数中的摩擦系数和黏聚力、围岩弹性模量、洞室间距作为影响因素,按照正交设计原理选取有代表性的组合方案,通过ANSYS软件进行地下洞室围岩稳定分析,并采用极差方法分析各影响因素对围岩稳定影响的程度,得到4种因素对地下洞室围岩稳定性影响程度由大到小依次为弹性模量、洞室间距、摩擦系数、黏聚力。
Taking engineering project for an example, this paper researched the influence factors on stability of underground cavern. Rock friction co- efficient, stick together force, elastic modulus and tunnel spacing were supposed as influence factors on surrounding rock stability, and the representa- tive combinations of these factors were choose in surrounding rock stability analysis. According to the orthogonal design principle, the influence degree of each factor was analyzed through the range analysis method. Four kinds of influence factors on the stability of surrounding rook of underground cav- erns have influence degrees from great to small in turn as the modulus of elasticity, cavern spacing, the cooffieient of friction, and cohesion.
