According to the results of experiments on the municipal solid waste (MSW), a series of formula are deduced to calculate the leachate free-faced headline curve. By means of static and dynamic finite element method (FEM), the stability of a wasteland during earthquakes is analyzed. It is demonstrated that the positions of the most dangerous sliding surfaces during earthquakes are fairly stable. Based on the above findings, this paper developed the Newmark method by increasing the precision to reckon the permanent deformation of wastelands during earthquakes. The method presented in the paper is not only of great importance to instruct the anti-seismic design of wasteland, but also valuable to the design of ordinary dams and embankments.

结合某城市固体拉圾填埋场在填埋过程中曾经发生滑坡的工程实例,进行了现场静力触探和室内试验。研究了垃圾填埋体的组成成分、物理性质指标、不固结不排水和固结不排水抗剪强度指标。在此基础上,对实际工程垃圾填埋体的边坡稳定进行计算,分析了填埋体中淋滤液的饱和度、边坡坡角和浸润线埋深对垃圾边坡稳定的影响。
