ANALYSIS OF SETTLEMENT MECHANISM AND MODEL FOR MSW BASED ON INTERIOR COLUMNAR LANDFILL TEST
-
摘要: 在室内配制了具有典型组分比例的固体废弃物,利用室内柱状沉降试验仪,在一定的淋滤条件下,进行长时间的废弃物填埋试验。定期测定废弃物在填埋全过程中的沉降值等指标。采用基于Gandolla计算模型,考虑废弃物瞬时沉降和长期沉降的特殊性,建立了考虑废弃物全过程沉降的复合沉降计算模型。利用柱状沉降试验观测数据,反演分析模型中的各计算参数。结果表明,应用复合沉降模型对填埋试验和现场试验分别进行的计算与观测值基本一致,说明沉降机理分析和计算模型的合理性。Abstract: Some kinds of refuse elements were mixed according to classic proportion indoors. Long time landfill test was done with interior settlement apparatus at stated leachating condition. In the course of whole landfill, settlement values were termly measured. On the basis of Gandolla model, considering the speciality of refuse immediate settlement and long term settlement, composite compressibility model considering refuse whole settlement was adopted. According to the measured date of columnar settlement experiment, the calculation parameters of model were back-figured. As a result, based on the composite settlement model, the calculated values and the measured values of landfill test and field test were basically accordant which showed that the analysis of settlement mechanism and the constructed model were reasonable.
