摘要

针对垃圾填埋场沉降计算问题，考虑垃圾土中有机物降解及对降解过程中重度变化，在张振营压缩量计算方法的基础上推导了垃圾土一维压缩计算的修正公式；通过垃圾土有机物降解试验和计算分析，研究了有机物的降解规律；以相同配比的垃圾土进行了垃圾土柱的沉降和计算参数试验，对推导的垃圾土一维压缩计算修正公式进行了验证。研究表明，修正的计算公式能考虑更多的影响因素，有机物的降解规律可以用Richards生物生长规律来模拟，修正的计算公式能够合理地计算出垃圾土沉降的过程。

Abstract

A modified calculation method based on Zhang Zhenying’s method has been presented to evaluate the settlement of landfills

considering the effect of degradation of organic content in solid waste and change of gravity density. The degradation law of organic content in solid waste is studied by degradation test and analysis. The modified method is verified by test of solid waste column and calculation parameters. The results show that the more complex effect can be considered in the modified method and the law of Richards growth function can be used as degradation law of organic content in solid waste; and the settlement of landfills in test can be calculated by the modified method reasonably.
