摘要
老垃圾填埋场竖向扩建时垃圾堆体的不均匀沉降控制是中间防渗衬垫系统设计的基础,正确计算和分析垃圾堆体的不均匀沉降将是老填埋场竖向扩建时成功与否的关键。研究了竖向扩建时垃圾不均匀沉降,并介绍了不均匀沉降的计算方法,结合工程实例对老填埋场竖向扩建时垃圾不均匀沉降影响进行了分析,从工程技术角度提出了相应的解决方案。
Settlement analysis of municipal solid waste （MSW） is one of the hot points and key points in the construction of landfill and in the field of geoenvironmental subjects. The control of differential settlement of MSW is the basis of design of middle liner system in the vertical expansion of existing landfill. It is very important to calculate and analyze the differential settlement of MSW correctly in order to ensure the success of vertical expansion of existing landfill. Aiming to the MSW differential settlement in the landfill of vertical expansion, calculation procedure is introduced firstly; and related application analysis is conducted with an engineering case. Finally, corresponding solving plans to control the differential settlement are presented from viewpoint of engineering technology.
