摘　　要：为了更好地计算填埋场垃圾土的热传导系数,提出了改进的垃圾土热传导系数计算模型,利用模型对试验数据进行模拟计算。结果表明,相对于串联模型、并联模型,改进的热传导系数计算模型能够准确地对垃圾土的热传导系数进行计算。模型可分析不同孔隙比和饱和度情况下垃圾土热传导的变化情况,模型计算出无锡桃花山填埋场垃圾土的热传导系数为0.0985~0.5644 W/(m·K)。In order to accurately calculate the thermal conductivity coefficient of MSW in landfill sites,an improved model for calculating the thermal conductivity coefficient was proposed.The simulation calculation of experimental data was carried out by using the model,the results indicate that the improved thermal conductivity calculation model can accurately calculate the thermal conductivity of MSW compared to the series model and parallel model.The model can analyze the variations in the thermal conductivity of MSW under different porosities and saturation,and the thermal conductivity coefficients calculated by the model from 0.0985 to 0.5644 W/(m·K).
