摘　　要：应用有限元数值分析方法模拟开挖施工过程中岩体随强度折减的位移变化,对开挖过程中岩体关键部位的位移时间序列进行尖点突变分析,以判别岩体位移的稳定性,从而分析岩体工程系统的稳定性。计算了有关的算例,并与其它计算方法作对比,验证了模型的合理性和有效性。The change of displacement with strength reducing of rock mass in the process of excavation is simulated by the finite element method. The cusp saltation analysis of displacement time series of key parts of the rock mass during the excavation is carried out to estimate stability of rock displacement, and to analyze stability of the rock mass engineering system. The related calculation examples are calculated and compared. Rationality and availability of the model are verified.

关 键 词：者体稳定 位移交变 算例
