摘要
通过对上海老港填埋场49号填埋单元进行的地面沉降监测,分析堆体沉降机理,建立了反映填埋场沉降特性的数学模型,结果表明:垃圾堆体在监测期内平均表面沉降量77.62 mm,沉降速率约为0.174 mm/d,模型预测监测堆体最终沉降量约为122 cm,未来5 a内还将有约7.9 cm沉降。
According to the settlement monitoring of No.49 landfill cell in Shanghai Laogang Landfill Site,the settlement mechanisms of waste dump were analyzed,and the mathematic model reflecting settlement characteristics of landfill site was established.The results showed that the average volume of surface settlement was 77.62 mm during the monitoring period,sedimentation rate approximately 0.174 mm/d.It was estimated that final settlement volume of waste dump was 122 cm by the model,and the settlement volume would be 7.9 cm in the next five years.
