河南辉县南湖水库浆砌石重力坝三维有限元分析

3D FEA(Finite Element Analysis) of Nanhu Reservoir Masonry Gravity Dam of Hui County in Henan

构建了以抗拉强度为损伤判断标准的浆砌石本构模型和三维有限元数值模型,分析了河南辉县南湖水库浆砌石重力坝在正常水位、设计洪水位、校核洪水位3种工况下的应力和变形情况,得出在不同工况下该重力坝的应力条件均在规范允许范围之内,但岸坡坝段容易出现拉应力区,需要增加监控措施的结论。

According to damage criteria based on strength of extension, it establishes the masonry constitutive model and 3 D finite element numerical model, analyzes the stress and deformation of Nanhu reservoir masonry gravity dam of Hui country in Henan under three working conditions： ordinary water level,designed flood level and check flood level. It concludes that under different working conditions, this gravity dam stress condition vary in the norm allowed band. The bank slope section needs more monitoring measures because of the easily appearing tensile stress.
