重力坝坝踵主拉应力区分布规律的探讨

Study on the law of diagonal tension stress distribution at gravity dam heel

本文应用有限元方法 ,计算了多种情况下的重力坝的应力 .以坝踵主拉应力区相对宽度为变量 ,探讨了重力坝坝踵主拉应力区的范围和应力分布规律 .

The tension stress distributions at the heel of four gravity dams in various conditions are calculated by using FEM.The main tension zone and law of stress distribution are investigated regarding the relative width of diagonal tension stress zone as variable.
