摘　　要：分析了典型的生活垃圾填埋场沉降经验模型(Lingetal.模型)、土壤动力学模型(Sowers模型和ISPM模型)的机理,并依据法国某城市生活垃圾填埋场为期4a的现场实际沉降量监测结果,率定了3种模型的模型参数,据此预测了相应填埋堆体的长期沉降情况,比较讨论了各模型预测结果的差异,并对预测结果进行了验证。结果表明,各模型短期预测结果与实测值偏差都不大,可作为填埋场短期附加库容估算的工具;从模型预测结果的准确性和便于应用2方面综合考虑,Sowers模型更为合适;对于填埋堆体高度大约为26m的填埋单元,最终覆土30a后填埋堆体沉降量可达填埋堆体高度的21%～27%。The typical empirical prediction model （Ling et al, model） and two soil mechanical models （Sowers model and ISPM model） were presented. Based on four years field data of a landfill site in France, the prediction models were applied, the values of parameters were offered, long term settlements of correspond in waste layers were predicated. Based on the model parameters, the comparison of different models was described and the prediction results were validated. The result shows that the short - term prediction results by 3 models are quite similar to the true values, the 3 models are good at calculation of excessive landfill capacity, the Sowers model is the best considering the veracity of prediction results and the facility of the model and there would be 21% to 27% settlement in 30 years for waste layer of 26 m in depth.
