摘要

摘要: 垃圾土的沉降是卫生填埋场沉降机理设计时需考虑的一个重要因素。通过对垃圾土沉降的分析，指出垃圾土的沉降机理相当复杂，与土的沉降机理不尽相同。分析了现有垃圾土沉降模型计算存在的问题。采用使观测值和预测值残差平方和达到最小的方法对Logistic模型求取参数，并应用于香港Sai Tso Wan垃圾填埋场及巴西Bandeirantes填埋场封场期后的沉降预测研究。结果表明，只要选取合适的参数，可以克服现有沉降计算模型的缺陷，大幅度提高垃圾土封场期后沉降值的预测精度。

Abstract: The settlement of the refuse is one of the important factors in sanitary landfill design.The settlement mechanism of refuse is analyzed.The complex refuse settlement mechanism is different of the soil settlement mechanism.The questions of the calculation of refuse settlement with existed models are analyzed.The method of the minimum square sum of the remainder between calculated results and measured ones is used to calculate the parameters of logistic model.The parameters are used to study the settlement prediction of Sai Tso Wan sanitary landfill in Hong Kong and Bandeirantes landfill in Brazil.Results show that the faults of existed refuse settlement models can be overcome and the prediction accuracy of the refuse settlement when the sanitary landfill was formed was greatly improved.
