摘要: 文章针对填埋场沉降计算问题,对垃圾压缩机理进行了研究,建立了常应力作用下的垃圾压缩模型。该模型将城市生活垃圾的压缩分为主压缩和降解压缩,其中,主压缩与压力有关,降解压缩与压力和降解条件有关。降解条件包括有机质含量和降解速率;结合对填埋场分级堆填过程的分析,建立了考虑降解和分级堆填影响的填埋场一维沉降计算方法,并对计算参数的取值方法进行了研究。Abstract: To solve the problem of the landfill settlement calculation,a model for MSW(municipal solid wastes) compression at constant stress was made.According to the model,the MSW compression was divided into the primary compression and the biodegradation compression.The primary compression is caused by upload.The biodegradation compression is influenced by both the stress and the biodegradation condition.The biodegradation condition includes the organic content and the biodegrading rates.A calculation method for landfill settlement was given,which takes into account both the influences of the biodegradation degree and the multi-loading process.The method of determining the calculation parameters is also examined.
