Based on clear boundary condition of dam shoulders , with rigid limit equilibrium vector method , baihetan hydroelectric power station dam shoulders anti - sliding stability analyzing program is compiled . then , by using above program , the anti - sliding stability of dam shoulders in different modes and different load patterns are calculated in respectively , and their stability is evaluated . the analysis results indicate that the anti - sliding stability of baihetan dam shoulders can meet the need of arch dam design 在查明坝肩抗力体边界条件的基础上,利用刚体极限平衡分析中的矢量法在文献[ 1 ]基础上编制了白鹤滩坝肩抗力体抗滑稳定性分析程序,并对白鹤滩坝肩抗力体的不同荷载情况下大块体的稳定性进行了评价,结果表明:白鹤滩坝肩抗力体的稳定性总体上达到了拱坝设计的要求。
