基于混凝土双轴强度准则的重力坝可靠度分析

Reliability analysis of gravity dam based on concrete biaxial strength criterion

目前重力坝的可靠度研究主要集中在建基面抗滑稳定等方面,对基于不同强度准则的重力坝可靠度分析研究成果相对较少.本文首先介绍了采用的双轴强度准则、广义随机空间内的可靠度分析方法,然后采用线弹性有限元法,对基于混凝土双轴强度准则的某重力坝可靠度进行了分析.

At present,the reliability research of gravity dams mainly focuses on the anti-sliding stability of the foundation surface,but there are little literatures on the reliability analysis of gravity dams based on different strength criteria.This paper first introduces the biaxial strength criterion adopted,reliability analysis method in generalized random space,then using the linear elastic finite element method,the reliability of gravity dam based on biaxial strength criterion is analyzed.
