摘要
应用有限元数值计算模型和刚体极限平衡稳定分析方法,考虑了安康水电站尾水边坡2号复合滑坡体岩体主要断层的结构面、混凝土抗滑桩、渗流、材料非线性以及地震惯性力等因素的影响,对该边坡体中3个典型可能滑裂面在有、无抗滑桩2种情况下的3种荷载组合工况的稳定安全性进行了计算分析.结果表明,在目前状态下该复合滑坡体是稳定的,但仍然需要加强对该滑坡体的日常安全监测和分析工作.
In consideration of the factors influencing the stability of the compound landslide, including the structural surface of main rock faults, concrete anti-slide piles, seepage, nonlinearity of material structure, and earthquake-induced inertial force, the stability and safety of three typical surfaces of the landslide with or without reinforcement by anti-slide piles, on which slip-induced cracks might occur, are calculated under three kinds of load combination by use of the finite element calculation model and the limit equilibrium method for rigid body analysis. The results show that the landslide is in the steady state, but the daily safety monitoring of the landslide should still be emphasized.
