摘要

摘要: 为了研究城市垃圾填埋场主压缩沉降对总沉降的影响，并对主压缩沉降作出准确的预测，通过对垃圾试样的压缩试验及理论分析，采用最小二乘法对试验数据的拟合曲线进行优化，建立了城市垃圾填埋场主压缩沉降的计算模型，该模型避免了主修正压缩指数难以确定的问题。结果表明：垃圾试样在整个压缩过程中的修正主压缩指数并非常数，修正主压缩指数与垃圾试样的初始干密度有关；利用垃圾试样初始干密度建立起来的主压缩沉降的计算模型对实际主压缩沉降进行预测，得到了较为满意的结果。

Abstract: In order to investigate the effect of primary compression settlement of municipal solid waste landfill on the total settlement,and make an accurate prediction on primary compression settlement,the computation model of primary compression settlement was established by the compression tests of waste sample and theoretical analysis,and using the least square method to carry on the optimization to the fitting curve with experimental data.Modified coefficient of primary compression was avoided with this model,which is difficult to determine.The results showed that modified coefficient of primary compression of waste samples was not a constant in the compression.It is related to initial dry density.The computation model of primary compression settlement was established using the initial dry density,which obtained a more satisfactory result by forecasting the actual primary compression settlement.
