| 摘 要： | 提出了一种在分步开挖的深基坑工程中计算受超固结影响的饱和粘土强度的方法，得出能同时反映开挖应力路径和应力历史的饱和粘土非线性应力应变关系。通过典型算例的有限元法分析，研究了软粘土深基坑性状及土的应力历史对其性状的影响。

| Abstract: | A method considering influence of overconsolidation on undrained strength of saturated clay is given for multi\|staged deep excavation. And so a modified nonlinear constitutive model is proposed, in which stress path and stress history can be considered. By FEM analysis of typical example, the behaviors of deep excavation in soft clay and the influence of soil stress history are investigated. |
