| 摘 要： | 针对老填埋场竖向加高扩容时垃圾堆体沉降机理的特殊性,将老垃圾堆体的沉降分为3部分:主固结沉降、次应力沉降、降解沉降,并研究各部分沉降的计算方法。结合工程实例,对沉降计算公式中有关参数取值进行探讨,并对扩容垃圾荷载作用下原垃圾堆体的沉降发展趋势进行分析,为扩容工程设计采取相应的沉降控制措施提供了依据。

| Abstract: | Aiming to the specialty of settlement mechanism of aging municipal solid waste (MSW) during the vertical expansion of existing landfills,the settlement of aging waste is classified into 3 parts:primary consolidation settlement, secondary stress settlement,and degradation settlement.The calculation methods of each settlement are studied,and the related parameters in the settlement formulas are discussed with the engineering case.Through calculation results,the settlement trend of aging waste due to the load of new filling waste above it is analyzed and some useul conclusions are put forward to conduct the design of expansion engineering. |

| Keywords: | municipal solid waste (MSW) existing MSW landfill vertical expansion settlement calculation secondary stress settlement and degradation settlement |
