摘要
为了解全库盘防渗复合土工膜的应力应变特性,结合新疆某山前倾斜平原全库盘防渗复合土工膜堆石坝,采用三维非线性有限元进行应力应变分析,并对库盘防渗复合土工膜进行了安全评价。由结果获得了竣工期和满蓄期水库防渗体系的应力应变分布规律和极值,可为工程设计提供依据,并提供行之有效的安全评价方法。
In order to obtain the stress-strain properties of the composite geomembrane seepage prevention of the whole bottom in piedmont sloping plain rockfill dam in Xinjiang, three-dimensional nonlinear finite element is used to ana- lyze its stress and deformation. And then it focuses on the safety evaluation of composite geomembrane seepage preven- tion. The stress-stain distribution law and extreme in completion and full storage period of the reservoir seepage system are obtained, which is helpful to provide reference for engineering design and effective safety assessment method.
