摘要

对填埋场振动台模型试验进行非线性数值分析，并与试验结果相互补充、印证，进一步考察填埋场的地震响应规律。研究表明，特殊的夹层结构形式导致水平地震作用下城市垃圾填埋场存在两个主要的响应频率，在这两个主要频率附近模型顶部取得峰值加速度响应；不考虑其他因素的影响，填埋场防渗层的地震永久位移与输入地震动的水平位移振幅近似呈正比关系；坡比是影响填埋场覆盖层和衬垫层永久位移最主要的因素。

Abstract

Based on the previous work of eight large scale physical model experiments of landfill conducted on shaking table

nonlinear numerical simulation for the test is performed subsequently; and the experimental and numerical results are verified and supplemented one another in order to further examine the characteristics of the seismic response of landfill. The follow results can be got: (1) Due to the special sandwich constructions

landfill has two main response frequencies; the peak acceleration responses at top of landfill are obtained in the vicinity of the two main frequencies under horizontal earthquake. (2) When other parameters are fixed

seism-induced permanent displacement of landfill liner is shown to be approximately proportional to the amplitude of input motion. (3) The inclination angle of landfill cover and base slope have significant effect on the critical sliding acceleration of cover and base liner system respectively.
