| 摘 要： | 以天津市华苑产业基地表土层为代表,分析其土的固结过程中微观结构的变化特征,并对微观结构量化参数的变化规律进行了总结。发现宏观上孔隙比和压缩系数随压力的增大而减小的规律与微观上土结构单元体的定向分维数、孔隙平均孔径、孔隙分布平面分维数的变化规律相一致。 |

| Abstract: | In this paper,the engineering properties of this kind of terrestrial soil and the change of microstructural character during consolidation are analyzed with the terrestrial soil of HuaYuan Industrial Base of Tianjin as the representativeone.The rule of changes on some microstructural quantitative parameters are summarized,Which found that the macroscopical hole ratio and the constrictive coefficient has been dinishied with the increase of load and the rule has been consistent with the changes of the orientation fractal dimension of the unit structure and the average diameter of hole and fractal dimension of pore distribution in microstructure. |
| Keywords: | surface soil layer microstructure consolidation |
