| 中文摘要: |
| 对苏州地铁某车站明挖基坑施工进行跟踪监测，及时掌握围护结构变形、支撑内力的变化动态，以指导施工确保基坑稳定。经过对比分析基坑有、无加固措施的变形和支撑内力的变化特征表明：基坑外水泥土搅拌桩加固措施的设置，可以有效地减小围护结构的水平变形，并且能够阻碍边坡滑移破坏面的发展，减小作用于地下连续墙上面的土压力，使得内支撑上的最大轴力减小。 |
| 英文摘要: |
| A field monitoring program was carried out for the open excavated project of a subway station in Suzhou, and the trends of the displacements of exterior protected construction and the inner forces of support were under control in time. The changes of characteristics on the displacements and inner forces of foundation pit with and without reinforced structure are analyzed respectively. The analytical results show that: the reinforced structures utilizing soil cement mixed diaphragm wall can diminish the horizontal distortion of exterior protected construction and the maximal value of inner forces because it can impede the development of slippage failure plane and diminish the soil pressure acted on the concrete diaphragm wall. |
