摘　　要：针对城市垃圾填埋场土工膜在各种荷载作用下产生拉应力过大破坏的问题,总结了垃圾填埋场土工膜在各种荷载下的应力-应变变化规律,提出了土工膜受边坡坡度改变、垃圾体堆填以及地震荷载影响时的受力特点和分析方法。并使用FLAC3D软件对土工膜的受力状况进行数值模拟,通过土工膜的应力云图,对土工膜拉应力进行分析。该结果对垃圾填埋场的环境保护和封场后的使用有一定的参考价值。In view of the problem of excessive tensile stress failure of geomembrane in municipal landfill under various loads, this paper summarizes the stress-strain variation law of geomembrane in landfill under various loads, and put forward the stress characteristics and analysis method of geomembrane under the influence of slope change, landfill and earthquake load. FLAC 3D software was used to simulate the stress of the geomembrane and analyze the tensile stress of the geomembrane through the stress cloud map. The results have certain reference value for the environmental protection and the use of landfill after closure.
