| 摘 要： | 为了探讨湿软土壤的剪切应力—剪切位移关系,对湿软土壤的剪切变形机制进行了分析。分析结果表明,由于土壤内部颗粒排列的不规则性和缺陷的存在使得其抗剪能力大大降低。可借助位错理论的某些方法来阐述湿软土壤的剪切变形机理。

| Abstract: | In order to obtain the relationship among shear stress, shear strain and time of wet and soft soils, analysis of shear deformation mechanism of soils is made. The results show that the shear strength can be decreased greatly due to defects and irregular arrangement of the particles in the soil. Dislocation theory can be used to describe the shear deformation mechanism of wet and soft soils. |
