摘要
本文讨论拱坝极限状态与极限承载力的分析方法.采用非线性有限单元法,分别根据最大正应力准则和脆性损伤模型,求得了某高拱坝的极限水压力超载系数,两种计算模型求得的该拱坝的破坏方式基本相同,极限超载系数接近,说明了建议的方法可以进一步用于拱坝的设计.
This paper deals with the analysis of limit state and bearing capacity of arch dams. Using non-linear FEM, based on maximum normal stress criterion and brittle damage model respectively, the rupture zones and limit water load factors of a high arch dam are computed. The comparison between the results from different constitutive models shows that the rupture zones of the arch dam are about the same and the limit load factors are basically equal. It is demonstrated that the suggested method may be used to the design of arch dams.
