摘　　要：针对双曲拱坝在各种工况静力荷载组合作用下的应力应变情况,通过有限元通用软件ANSYS对其进行计算分析,研究中考虑了溢流面的影响及坝肩的应力要求,为了看清坝内温度的影响,采用了分部加载方法,使温度产生的应力和应变更加明显呈现,可以清楚认识拱坝中温度控制的重要性。This article in view of double-curvature arch dam,under each kind of operating mode static load combination function,has carried on the stress strain computation analysis through finite element common software ANSYS.In the research,it has considered the influence of the flow surface,and stress requirements of the dam shoulder.In order to catch the temperature influence of the dam,it uses the method about branch and increasing in order to make the stress and the strain which the temperature produces obvious ...
