摘　　要：有限元等效应力法是拱坝设计新规范规定的两种强度校核方法之一 ,也是新规范规定的拱坝强度设计标准 .文中借助于有限元软件ANSYS7.1 ,对块泽河电站拱坝进行有限元计算及其等效应力计算 ,并按规范规定的相应强度标准进行校核 .介绍有限元等效应力法在拱坝设计中的运用实例 .The finite element equivalent stress method is one of the two checkout critera ordered by the new design specification for concrete arch dams, and it is a new strength design criterion too. The finite element stresses and the finite element equivalent stresses in the arch dam in KUIZHE river power plant are calculated by using today's popular international finite element software ANSYS7.1, and the latter is checked by the corresponding strength criterion in the design specification. An example of the finite element equivalent stress method in engineering design practice is described.
