摘　　要：应用局部非协调网格协调位移计算方法对古田双口渡砌石拱坝进行了有限元应力分析,并采用在有限元内力法基础上提出的改进的拱坝应力分析方法对其进行等效应力的分析计算,计算成果相比较,二者结果相似,应力分布规律相同。In this paper, the compatible displacement method for treatment of the locally incompatible mesh is applied to the Shuangkoudu arch dam stress analysis, it also used the improved method for analysis of arch dam equivalent stress which based on the finite internal force method to calculate Shuangkoudu arch dam equivalent stress. To compare the results, we find they have the similar stress distribution.
