| 摘 要： | 首先以分别加载的方式对以重庆市城市生活垃圾典型组分为依据配制的垃圾试样进行不同应力水平的室内压缩蠕变试验,进而根据蠕变元件的基本性质和试验过程中试样反映出的变形特征,利用HK和PTH蠕变模型对生活垃圾的蠕变曲线进行拟合,并总结得出蠕变模型的基本参数。研究表明,HK和PTH模型对试验数据的拟合程度都比较好,此两种模型对于垃圾填埋场的容量计算和沉降规律研究具有一定的参考价值。 |

| Abstract: | To study the creep model of the Municipal Solid Waste(MSW)in Chongqing City,samples were confected for creep compressive indoor test.Two types of creep models,named HK Model and PTH Model,were used to fit the test data and obtain the creep curves based on the theory of creep models.The model parameters are presented.The results indicate that the fitting curves of HK Model and PTH Model are both suitable for the simulation of MSW's deformation,and both models are valuable for calculation of site capacity and landfill settlement. |
| Keywords: | Municipal Solid Waste(MSW) creep compressive test staged loading |
