Based on rigid body method and finite element method , the deep stability against sliding of yunfeng dam was analyzed in details . the results show that its safety factor along the fault is on the low side . on account of some parameters in the computation modules were indeterminate , the results obtained could not reflect the real safety situation of yunfeng dam 在對其空間結構進行細致分析的基礎上,提出將51 ~ #和52 ~ #兩個壩段合并在一起建立物理模型,綜合考慮各阻滑面和側面基巖的抗剪斷強度的作用,分別按剛體法和有限元法對其抗滑穩(wěn)定進行復核計算。
