| 摘 要： | 根据原位十字板试验过程中,对饱和软粘土扰动导致其不排水强度降低的事实,应用圆柱孔扩张理论,假设饱和软粘土在塑性阶段满足Tresca屈服条件,提出了一种基于饱和软粘土灵敏度的扰动度函数D。考虑在塑性区内不排水强度su是扰动度D的线性函数,得到了考虑扰动的圆柱孔扩张的弹塑性解答。

| Abstract: | According to the fact that the undrained shear strength decreases in the field vane test,applying the cylindrical expansion theory and assuming that the saturated soft clay satisfies Tresca yield criterion,the disturbance degree function D is given on the basis of the sensibility of saturated soft clay.Considering that the undrained shear strength is the linear function of the disturbance degree D in plastic region,the elastic-plastic solution of the cylindrical expansion has been gained. |
