摘要

强度折减弹塑性有限元法经常被用于边坡稳定分析中

而用于固废填埋场稳定性分析中的目前并不多见。本文对考虑衬垫系统的固废填埋场稳定性进行数值模拟

所得结果与极限分析上限法的分析结果基本一致

验证了本文分析方法的有效性。分析表明

当固废填埋场堆体长度小于一定值时

安全系数随着堆体长度的增大而增大

当填埋体长度超过一定值后

填埋场的安全系数不再变化;随着填埋体长度的增大

填埋体的破坏模式从开始的平动-平动组合破坏模式

变为最后的转动-平动组合破坏模式。

Abstract

Strength reduction elastoplastic finite element method is often used for slope stability analysis

but this method is seldom used in the stability analysis of landfills.In this paper

the stability of the landfill with liner system is analyzed by the elasto-plastic finite element method. In addition

the stability of the landfill based on the strength reduction finite element method is finally verified by comparing with the limit analysis method.The analysis results of the two methods are basically the same.It shows that for the landfill with liner system

the factor of safety the increases with the increase of landfill length and finally reaches a certain value.Along with the rising of the landfill length

the failure mode of landfill transits from the translationtranslation combined failure mode into the rotation-translation combined failure mode.The result obtained by the strength reduction finite element method and the upper bound limit analysis method are similar.
