| 摘 要： | 上、下界面的不平衡摩擦力将导致填埋场边坡上的土工防渗膜承受拉应力．垃圾填埋体内淋滤液水位的高低将对防渗膜上、下界面摩擦力的大小产生影响，进而影响防渗膜承受的拉应力，文中利用作者推导的一种确定防渗膜拉应力大小的新方法对其进行了计算．对某填埋场实例的计算结果表明，淋滤液水位的存在将改善防渗膜的工作性态．

| Abstract: | The geomembrane on landfill slope might bear tensile stress due to disequillibrium between the frictions of its super-surface and sub-surface. Meanwhile, the leachate level in the fillmass will influence the frictions, and therefore influence the tensile stress of the geomembrane. A new method is used for calculating the stress of the geomembrane. The calculation of a landfill presents that the existence of leachate level will improve the working situation of the geomembrane. |
