摘要
西安市黑河水库右坝肩变形体是在旋转变形条件下形成的 ,这样 ,对它的稳定性评价必须按空间问题来考虑 ,要用三维分析方法来计算它的稳定性。鉴于目前的三维计算方法比较复杂 ,得出的结果实用性不大 ,本文首次编制了三维刚体极限平衡法程序 ,该程序既能计算稳定系数 ,又能计算出相应稳定系数下的滑坡推力。应用该程序计算黑河水库右坝肩变形体的稳定性 ,得出的结果与实际相吻合 ,同时又为工程治理提供了依据。
The deformed rock mass at the right abutment of the Heihe Reservoir of Xian City was formed by rotation. Thus, the analysis of its stability must be performed by three dimension method. However, current calculation methods are difficult to be put into practical use due to their complicity. This paper writes a 3-D program of the rigid limited-equilibrium method by which both the stability coefficient and the pushing force of landslide can be computed. Then, it is applied to the stability analysis of deformed rock mass at the right abutment of Heihe Reservoir. The result correlates well with real case and provide evidence for the engineering prevention.
