| 摘 要： | 针对重力坝坝踵应力集中问题,在研究分析现有方法的基础上,提出重力坝坝踵等效应力法。这种方法思路是:承认离开坝踵一定区域外部分由有限元计算所得的结果,在坝踵部位用等效应力替代原有计算值。则此方法可以大大降低应力集中的影响且计算简便,同时具有一定精度,所以该方法有一定实用价值。

| Abstract: | Aiming at gravity dam heel stress concentration probIem, based on the research and analysis of the existing methods, a new method which named dam heel equivalent stress method was put forward. This method is： accept the stress result which is far away from dam heel got by finite element method, in dam heel area stress result was replaced by dam heel equivalent stress. This method can reduce the effect of stress concentration and simple, also it is proved to be precision. So the method has a certain practical value. |
