| 摘 要： | 从场区所发育混合土的特征入手,首先进行混合土的现场天然密度测定,然后系统地阐述天然混合土压缩变形试验全过程的关键技术,即荷载等级设置、正应力荷载等级稳定时间与稳定量级、天然状态压缩变形试验s- t、p-s曲线特征、利用时间平方根法求算固结系数G_v等,形成了一套较为完整的混合土压缩变形参数量化技术, 为类似的压缩变形试验提供了完整的参数量化操作方法,具有一定的参考价值。 |

| Abstract: | From the distribution property of mixed soil at construction site, the natural density has been determined firstly, and then the paper has systematically expatiated the key technique in whole process of natural mixed soil compression-deformation test. That is, setting of load grade, stabilizing time and magnitude of normal stress, characters indicated by result of s-t & p-s curves in compression-deformation test under natural circumstances, and Cv concretion coefficient evaluated by time square root, etc. It has been formed a set of complete technique of parameter quantification in mixed soil's compression-deformation test. It could be taken as a reference to apply whole operation for parameter quantification in the similar compression-deformation tests. |
| Keywords: | high filling body mixed soil compression-deformation test parameter quantification airport |
