摘　　要：对毛坦砌石拱坝进行了温度场和应力场全年仿真计算;分析了砌石拱坝上游拱冠梁底部拉应力的成因及温度因素在温降期对拱坝应力的影响。为同类砌石拱坝冠梁底部强度设计及安全性提供了一种应力分析方法和理论依据。Annual analogue simulation of masonry arch dam was done by using finite element method. The cause of the pulling stress of crown cantilever and influence of the thermal stress were analyzed. An algorithmic method to design and analyze the safety of this part of the dam was given.
