| 摘 要： | 文章以扩展的修正剑桥模型为土体的本构关系,并且考虑土体与支护之间的相互协调作用,采用二维平面有限元法对上海某地铁车站深基坑进行模拟计算,并与实测土压力及朗肯土压力作对比分析。计算和实测结果比较表明,有限元法可以较好地模拟软土深基坑的实际施工工况,能够取得比较符合实际的效果。 |

| Abstract: | The extended modified Cam-clay model is used as the soil constitutive relationship,and the interaction between the soil and the retaining wall is considered in simulating the excavation of the deep foundation ditch of a station of the Shanghai Subway.The results calculated by the plane strain FEM have been compared with the field test results of soil pressure and the Rankine soil pressure,which indicates that the FEM is suitable for simulation of deep foundation excavation. |
| Keywords: | modified Cam-clay model constitutive relationship FEM deep foundation ditch |
