摘　　要：为展开水库全库盘防渗土工膜应力应变分析,以对水库防渗安全及稳定运行提供保证,以奥吞勒克水库为例,应用FLAC3D商用软件构建三维有限元模型并展开土工膜受力变形单元模拟,分别对坝体土工膜受力变形、混凝土面板应力应变、库盘及全库盘防渗土工膜受力变形展开模拟分析。根据分析结果看出,水库在竣工期以及满蓄运行期间所构建起的全库盘防渗体系应力应变极值均合理可控,结构受力平衡稳定,水库防渗安全有保证。In order to carry out the stress and strain analysis of the impermeable geomembrane in the whole reservoir and ensure the safety and stable operation of the reservoir,FLAC3D commercial software was utilized to construct a three-dimensional finite element model and simulate the stress and deformation characteristics of the geomembrane.The stress and deformation of the geomembrane within the dam body,as well as the stress and strain analysis of the concrete face slab,are conducted separately.Additionally,simulations and analyses are performed on both the geomembrane within the reservoir and the entire reservoir itself.The results indicate that the extreme stress and strain values of the entire reservoir anti-seepage system,both during construction and full storage operation period,are within reasonable and contrllable limits.The structural forces remain balanced and stable,ensuring the anti-seepage safety of the reservoir.
