水库大坝不同防渗体ABAQUS有限元模拟分析

ABAQUS Finite Element Simulation Analysis of Different Anti-seepage Bodies in Reservoir Dam

坝体防渗加固是当前地方性水利工程面临的主要问题之一。以山东临沂河西水库为分析对象,利用ABAQUS有限元模拟分别对黏土心墙和复合土工膜心墙在应用后的各项参数进行了对比分析。经对比,发现复合土工膜心墙在抗变形、防渗效果、降低浸润线高度等关键参数中均表现较好,其中防渗效果更是出现了一个数量级的差距。

Dam anti-seepage reinforcement is one of the main problems faced by local water conservancy projects at present.Taking Hexi Reservoir in Linyi as the analysis object,ABAQUS finite element simulation was used to compare and analyze the various parameters of clay core walls and composite geomembrane core walls after application.Through comparison,it was found that the composite geomembrane core wall performs well in key parameters such as deformation resistance,anti-seepage effect,and reducing the height of the infiltration line,among which the anti-seepage effect shows an order of magnitude difference.
