摘　　要：指出了我国现行拱坝设计规范中存在的问题,根据若干已建拱坝的有限元等效应力分析结果,探讨基于有限元等效应力法的应力控制标准,提出了考虑建筑物等级的压应力设计准则和综合拉应力设计准则.Some problems existing in the current code for arch dam design in China are pointed out. According to the analysis of equivalent stress of typical arch dams built in China, new design criteria based on finite element equivalent stress analysis are proposed, in which the importance or grade of structures is considered in the compressive stress criterion, and, as a control of tension field along the direction of dam thickness, the limit ratio of the maximum tensile stress to compressive stress of the same section is included in the tensile stress criterion.
