为确定垃圾填埋场垂直防渗墙的受力变形特性以及能否满足变形要求，以江苏省常州市夹山子工业垃圾安全填埋场防渗墙工程为例，根据其地层地质情况，采用 ANSYS 有限元分析软件对以膨润土－水泥－煤灰为主料的防渗浆材浇筑而成的塑性防渗墙进行非线性应力变形数值分析。分析得出该防渗墙的应力及水平位移在墙底达到最大值，在深入黏土部位出现增加；墙体应力随墙高等比例增加，且没有出现拉应力，墙体的应力变形均满足要求；防渗墙最大水平位移同墙高的二次方呈线性关系，计算结果具有合理性，为垃圾填埋场防渗墙工程设计与运营提供了理论依据。

2.School of Civil Engineering &Architecture,Changzhou Institute of Technology,Changzhou 21 3002,China) In order to make sure that the deformation behavior of waste landfill’s vertical diaphragm wall meets re-quirements,we conducted nonlinear simulation on the deformation and stress of plastic diaphragm wall using AN-SYS.The diaphragm wall of industrial waste landfill at Jashanzi in Changzhou,Jiangsu province was taken as an example.The plastic diaphragm wall was poured from anti-seepage slurry with bentonite,cement,and fly ash as main materials.Results reveal that the stress and deformation of the diaphragm wall meet the requirements.The stress and horizontal displacement both reached maximum at the bottom of the wall,the principal stress of wall in-creased at the clayey stratum,and no tensile stress was found;the maximum horizontal displacement of the wall is in linear relationship with the square of wall height.The results are reasonable and provide theoretical basis for en-gineering design and operation of waste landfill’s diaphragm walls.
