| 摘 要： | 结构性是土最为内在的根本特性之一.通过对天津地区软土进行的结构性试验研究表明,结构性对土工特性有很大的影响.表现为压密特性、孔隙水压力的变化和剪切应力应变关系均与应力水平有密切联系.通过SEM图像分析表明,微观结构为絮凝结构的土粒间力(其宏观表现为结构屈服应力)小于外力时就发生破坏,而一旦进入团粒结构,土体的变形发展缓慢.

| Abstract: | The structural property is one of the intrinsic characteristics of soil. The experimental study on the structural property of soft soil of Tianjin region has been carried out, which is verified that the structural property has strong effects on its engineering characteristics. Owing to the structure in such soil, its characteristics of compressibility, the change of pore-pressure and shear stress-strain relationship all depend on stress level. The analysis of Scanning Electronic Microscope shows that the failure happens when the inner particles force of flocculent structure is less than outside force, but the development of soil deformation with agglomerate structure is slowly. |
