摘要
结合沙牌ＲＣＣ 拱坝地形、地质条件，针对含断续节理裂隙岩体的强度呈现明显方向性的特点，建立了包络多种破坏模式的强度模型。运用三维非线性有限元数值分析方法，研究坝肩（ 基） 岩体的超载特性与整体稳定安全储备，并对坝肩（ 基） 岩体及裂隙面强度参数进行敏感性分析。
Sapai RCC arch dam is one of the principal engineering projects in the national eighth and ninth Five Year Plan.Using 3D nonlinear finite element method dealing with multi damage mode models,this paper has conducted the stability evaluation and over load characteristics of the dam.Respect to the geological condition of the RCC dam,this paper also studied the influence of sparsely distributed fracture in rock mass to the dam stability.
