摘　　要：垃圾填埋场中垃圾土的降解是垃圾填埋场沉降的主要原因,而垃圾填埋场的沉降对HPDE衬垫膜的受力和工作状态有显著的影响,HPDE衬垫膜的设计需要考虑垃圾填埋场沉降的作用,文章通过垃圾土中有机物的降解试验和垃圾土柱沉降试验,推求了考虑垃圾土压缩和降解的变形计算方法,进行了垃圾填埋场的离心模型试验,探讨了垃圾填埋场中垃圾体的变形分布规律和衬垫膜的受力特征,对衬垫膜的设计计算方法进行了研究。The degradation nf organic part in solid waste in landfills is an important factor in its deformation. And the influence of landfill＇s settlement nn the stress and working condition of HPDE liner is obviously. The settlement of landfills needs to be considered in the design of HPDE liner. In the paper, calculation method of settlement of landfills is presented based on the tests of degradation of organic part in solid waste and solid waste column, The behaviors of HPDE liner and deformation of solid waste in landfills are studied based on centrifugal model tests, And the calculation method used in the design of HPDE liner is studied.
