摘　　要：本文以建筑在复杂岩基上的某重力拱坝为例，介绍了采用数值分析方法研究拱坝与两岸坝肩岩体联合作用条件下的变形过程、应力状态和转异特征的原理和方法，分析实例说明，采用这种综合分析方法可以较为接近实际地分析建筑于复杂地基之上的拱坝及坝肩岩体、断裂结构面的变形、应力状态及转异特征，为探索解决这一复杂综合问题提供一条有效的途径．In this paper, a certain gravity arch dam built on complex rock foundation is refered as an example, to analyze principle and method for studying the deformation process. stress state and anomalous characteristics of integrity of arch dam and its abutments. It shows that the deformation process. stess state and anomalous characteristics of arch dam, its abutments and faults can be achieved in correspodence with actual state by using this synthetic method. An effective method for solving this synthetic and complicated problem has been discussed in this paper.
