根据城市生活垃圾室内外试验结果，提出了确定浸润线自由面的方法．通过静力和动力有限元计算，对某填埋场边坡进行稳定分析，给出了在地震过程中每一小时段的稳定安全系数．结果表明，在地震过程中，最危险滑动面的位置比较稳定；在此基础上，对Newmark方法进行了改进，使之建立在比较精确的基础上，得到了填埋场在地震作用下的永久位移，对填埋场的抗震设计具有重要的指导意义．这一方法对一般坝体的工程抗震也有很大的参考价值．   相似文献

IntroductionStability of municipal solid waste (MSW) was not a major concern early because waste instability was considered as an operational problem that can be remedied by replacing the waste in its original position. However, with the introduction of liners and leachate collection and removal systems (LCRS), the integrity of the liner and LCRS may be concerned. Instability or displacement of a wasteland may result in failure of above system and contamination of groundwater or surface wa…  相似文献
