中文摘要：
对典型构型填埋场的二维地震响应进行了详细计算，目的是考察不同强度地震动作用下填埋场的稳定性，评价影响填埋场稳定性的主要因素，及各因素之问的相对重要性。计算结果显示：（1）覆盖层的稳定性主要依赖于垃圾土的材料属性、填埋场高度、输入地震动的频谱特性、以及场地条件等参数；（2）衬垫层的稳定性取决于输入地震动的加速度峰值、卓越周期和填埋场的基本白振周期。
英文摘要：
2D seismic response of landfills is explored in detail, in order to investigate stability of landfills at different intensity of earthquake shaking, as well as to evaluate the relative importance of different factors influencing the seismic response of landfills. The results indicate that the stability of landfill cover depends primarily on wastes properties, landfill heights, spectral characteristics of input motions, and site conditions; however, for base sliding case, the stability varies significantly due to the peak acceleration, period of input motions, and the basic period of landfill.
