摘　　要：本文针对连拱坝的动力特性，提出了子结构交叉综合法的计算方法．在这种计算方法中，以一个支墩与相邻两拱形成动力子结构，以子结构截尾模态作为基向量。In this paper the cross synthesis method for modal analysis of multiple arch dams is proposed. In this model the substructure is formed by a buttress and two neighboring arches and every substructure is crossed each other. The truncated modal vectors of substructure are employed as basic vectors for Rayleigh Ritz principle. Two examples are given for illustration.
