| 摘 要： | 利用土体微细结构光学测试系统对黏性土在压缩过程中微细结构变化进行了定量分析研究,提取并分析相关微细结构特征参数。研究表明,从微细观角度来看,黏性土的压缩性主要受3个因素影响:土体颗粒自身形态的变化、土体颗粒排列方式的变化以及土体孔隙形态的变化。

| Abstract: | A quantitative analysis was performed of the microstructure variation of a cohesive soil during the compression process by use of the optical measurement system for microstructure of soil,and some characteristic parameters for the microstructure were obtained and analyzed.The result shows that the compressive behavior of the cohesive soil is mainly affected by three factors,(including) the variations of shapes and arrangement of soil particles and pore shapes of soil. |

| Keywords: | cohesive soil microstructure compressive behavior degree of polymerization distribution and fractal dimension |
