| 摘 要： | 通过对国内外垃圾土沉降研究方法进行分析，讨论了垃圾填埋场的沉降计算方法和数学模型，认为垃圾土在填埋期的压缩变形可用土力学现有的分层总和法进行计算，而长期运行垃圾体的沉降受垃圾土的次压缩特性和有机物降解的共同影响；深圳下坪固体废弃物填埋场垃圾体的沉降量与计算结果表明，有机物降解是垃圾体沉降的主要因素。

| Abstract: | This paper discusses the waste landfill subsiding calculation methods and mathematic model by analyzing the method of rubbish soil subsiding research home and abroad and considers rubbish soil compression deformation in landfilling period can be calculated by summing up the individual layers through applicable soil mechanics process, while long-time rubbish soil subsiding is jointly affected by its secondary compressing characters and organic matter degradation. Subsiding quantity of rubbish in Shenzhen Xiaping Solid Waste Landfill and the calculated results show organic matter degradation is the main factor resulting in rubbish subsiding. |
