摘　　要：针对纳夜水库工程的挡水坝,采用ABAQUS数值模拟软件,对坝体的孔隙比、饱和度和孔压等渗流参数进行分析,提出具有针对性的防渗处理方案,并借助有限元软件对加固效果进行数值分析。结果表明:当坝体浸水后,坝体的孔隙比、饱和度和孔压等均增大;隔渗墙布设后,隔渗墙前后孔隙比和饱和度等出现突变,隔渗效果明显,满足工程正常运行的要求。Aiming at the dam of Naye Reservoir project,ABAQUS numerical simulation software was used to analyze seepage parameters such as pore ratio,saturation and pore pressure of the dam body,and a targeted anti-seepage treatment scheme was proposed,and the reinforcement effect was numerically analyzed by finite element software.The results show that the pore ratio,saturation and pore pressure of the dam increase when the dam is immersed in water.After the installation of the seepage barrier wall,the pore ratio and saturation of the front and back of the seepage barrier wall appear sudden changes,and the seepage barrier effect is obvious,which can meet the requirements of normal operation of the project.
