| 研究垃圾土的压缩应变模型参数对填埋场的设计、建设以及管理是至关重要的。本文根据重庆市城市生活垃圾的组成特点,用配制的垃圾土进行单级长期加载压缩试验。试验结果表明:试验初期压缩应变量较大,经过一个加速期以后,应变趋于稳定。压缩应变速率在24 h之前变化较大,24 h后趋于平缓,建议用24 h的压缩应变代替极限压缩应变。根据垃圾土压缩应变特点,用广义开尔文模型对试验结果进行数据拟合,得到模型元件参数。 |

| It is important to carry out research on the compress strain model parameters for municipal solid waste,which is related with sanitary landfill design,building and management.In this paper,according to the compositional characteristics of Chongqing municipal solid waste,the sample was confected and the compress test was carried out.The results showed that in the initial stage the compress strain is higher and after an accelerating period the strain became steady.The strain speed was great before 24 hours an... |
