摘要
利用有限元法及三维实体任意截面数据处理技术,建立了高拱坝坝肩稳定安全系数计算分析方法,并编制了相应的计算和处理程序.通过对某高拱坝动力稳定性的分析计算,给出了拱坝坝肩在3个典型高程分别沿两滑移面交线方向、侧滑面及底滑面滑动的最小安全系数.
A safety factor method for calculation and analysis of the stability of the abutment of arch dams was developed based on the finite element method and 3D dataprocessing technology for arbitrary cross sections of solid masses, and corresponding programs were compiled. By dynamic stability analysis and calculation for an arch dam, the minimum safety factor for sliding along the intersecting line of two sliding surfaces, the side sliding surface and the bottom sliding surface of the arch dam abutment was calculated respectively for three characteristic elevations, and the minimum safety factor was obtained.
