| 摘 要： | 以苏州七子山垃圾填埋场扩建工程为例，利用数值模拟和分层总和沉降法分析老场垃圾堆体在新填埋堆体作用下的“二次沉降”规律。结合老场垃圾土的现场试验数据，利用有限差分软件FLAC3D对堆载过程中老场垃圾土的沉降进行了模拟。结果表明，在新场封场时，老场沉降呈“穹隆”状；最大沉降发生在中间部位，最大沉降量约为老场堆体厚度的20%左右。数值分析计算结果约为分层总和法计算结果的1.2倍。

| Abstract: | Taking the expansion works of Qizishan rubbish landfill yard in Suzhou as an example,we analyze the secondary settlement regularity of original landfill caused by new landfill expansion work using numerical simulation and layer-wise summation method.In the combination of in-site test data of original solid waste,the settlement of original solid waste is analyzed by finite differential software FLAC3D.The analysis result shows that the settlement of original landfill at completion time of new landfill is in ... |
