摘要:
拱坝等水工混凝土结构体积庞大结构复杂,确保其安全稳定意义重大。针对拱坝整体安全分析问题,采用D-P屈服准则并利用超载法进行弹塑性有限元计算,根据特征点位移突变判据研究拱坝的整体健康状态。以某高拱坝为例进行有限元计算分析,计算结果表明其安全系数K应在5~5.5之间,并证明了有限元超载法在拱坝整体安全分析中的可行性。
Abstract:
Hydraulic concrete structures such as arch dams are huge and complex, so it is of great significance to ensure their safety and stability.Aiming at the overall safety analysis of arch dams, the D-P yield criterion and the overload method were used to calculate the elastic-plastic finite element method.The overall health state of arch dams was studied according to the displacement catastrophe criterion of characteristic points.Taking a high arch dam as an example, the finite element analysis was carried out.The calculation results showed that its safety factor K should be between 5 and 5.5, and the feasibility of finite element overloading method in the overall safety analysis of arch dam was proved.
