摘　　要：在研究大型地下洞室围岩稳定性时,综合考虑了围岩强度和刚度、洞室高度和埋深、水平向地应力及其相互间距等影响因素,采用FLAC3D软件进行了16个工况的数值模拟计算,建立了影响地下洞室稳定性的层次分析法模型,对影响稳定性的各个指标因素进行判断矩阵的构造、特征向量的求解以及一致性的检验。这种分析方法可以从总体上对各因素进行排序,为将来预测地下洞室围岩稳定性提供必要的依据。In this stability analysis of underground caverns, influencing factors, such as mechanical parameters of surrounding rock masses and height, depth and spacing of caverns and so on, are considered. This paper performs numerical simulations of 16 operating modes, and establishes a model of the analytic hierarchy process of stability analysis for large-scale underground caverns. The process includes construction of decision matrices, solution of characteristic vector and verification of consistency. The method can be used in general sequencing for influencing factors of the stability of surrounding rock masses and provide a basis for the stability forecasting of underground caverns.
