【摘要】 本文采用Mazars模型提出了重力坝岩基的整体损伤因子。通过推导损伤和孔隙水压力及黏聚参数的关系,将求整体损伤因子的问题化为一个优化模型。并在同时使用了迭代法对重力坝岩基的损伤场与应力场的耦合的过程进行解耦运算,提高了计算的精度。并进行了实例的验证,比较研究考虑和不考虑渗透水压影响下的整体损伤的差别。更多还原

【Abstract】 This paper defines the overall damage of rock foundation and gravity dam based on Mazars model.By deducing the relationship of pore water pressure and cohesive parameters,the overall damage can be obtained by solving transformed optimal model.And this page explains how to use iterative method to decouple the coupling relations between damage factor and strain in order to improve precision.And an example is given to verify the proposed model and compare the difference of overall damage between considering and not considering seepage water pressure.更多还原
