摘要: 采用有限元进行重力坝坝体应力分析时,坝踵应力的取值一直是坝工界长期关注的问题。基于有限元等效应力的思想,提出了一种新的简化等效方法,通过限制网格的大小来计算坝踵应力,得到的应力值可作为设计的参考。

Abstract: Determination of the stress of gravity dam is a long-term issue in dam design. This paper, base on the thought of equivalent stress, put forward a new simplified method as well as a thought that stress of heel can be calculated by FEM with control of the grid width.
