| 中文摘要: |
| 对上海淤泥质软土进行真三轴试验，研究土在三维应力状态下的应力和应变的变化规律，试验结果表明：固结压力和中主应力对土的性质有很大影响，特别是中主应力对土的影响大。在试验基础上，建立了考虑中主应力影响的非线性模型。 |
| 英文摘要: |
| The characteristics of soft soil are studied using a new testing facility under 3-D stress state. It is found that consolidation pressure and particularly the intermediate principal stress have great influences on characteristics of soil. The nonlinear model taking the effect of intermediate principal stress into account is established. |
