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。
Based on the dislocation theory, the shear stress-shear strain-time relationship of wet-soft soil was derived. Theoretical analysis and experimental results show that soil shear stress has a power function with shear rate, and the relative shear stress level is only related to shear displacement but not to shear velocity.
