Base on case studies of Jinkou aerobic landfill restoration project in Wuhan,we compared and analyzed the applicability of Park model(biodegradation settlement model),Ling model(hyperbolic model),Yen model(Logarithmic sedimentation model) and Sower model by parameter fitting,then selected the most suitable model to predict the landfill settlement in this project.The main results were as follows:biodegradation settlement model is more applicable than others.In Sower model,C,e parameter was 0.004 ～ 0.001 3 in aerobic remediation site,0.002 ～ 0.003 in closure site separately.In biodegradation settlement model,parameter k was 0.6 ～ 2.1 in aerobic remediation site,0.15 ～ 0.45 in closure site correspondingly.The time of dynamic settlement rate from background rate to less than 5 cm/a was 1.52,1.54 and 0.15 years in different subarea in Jinkou landfill respectively and they all satisfied with the requirements of area utilization.%通过武汉市金口生活垃圾填埋场好氧修复工程案例研究,对比分析Sower模型、Park生物降解沉降模型、Ling双曲线模型和Yen对数沉降模型的适用性,采用模型参数拟合的方式分析比较了各沉降模型的参数,并采用适宜的沉降模型对本工程案例沉降进行预测.结果表明:生物降解沉降模型相对于其他模型更适用于好氧修复过程沉降预测;Sower模型中Cae参数在好氧修复区为0.004～0.0013,封场区为0.002 ～ 0.003.生物降解沉降模型中k参数在好氧修复区范围为0.6～2.1,封场区为0.15 ～ 0.45;填埋各区动态沉降速率达到小于5 cm/a需要的时间分别为1.52、1.54、0.15 a,满足场地利用标准.
