| 摘 要： | 从位错理论出发导出了湿软土壤的剪切应力—剪切应变—时间关系。理论分析和试验结果表明土壤剪切应力与剪切速度成幂函数关系;与其本身可能抵抗的最大剪应力相比的相对剪应力水平只与剪切位移有关而与剪切速度无关。

| Abstract: | The shear stress - shear rate - time relationship of wet and soft soils is determined from the point of view of dislocation theory. Theoretical analyses and experimental results show that shear stress of soils is a power function of shear rate. The relative shear stress comparing with shear strength is related only to shear displacement and not to shear rate. |
