| 摘 要： | 依据周边环境、地质条件与基坑挖深，对苏州凤凰国际书城基坑采用钻孔灌注桩加内支撑支护方案。由于该基坑紧邻地铁车站，周边环境复杂，依据有关规范制定了基坑施工监测方案，并对监测结果进行分析，包括深层水平位移、地下水位降深、地铁车站变位等。对于地下三层基坑的止水帷幕优先选择“两次提升、两次下沉”的三轴深搅桩施工工艺；局部落深区小范围内的第Ⅰ承压水位的降低对周边建筑物的影响不大。结论可作为区域性围护设计方案选择的参考。

| Abstract: | The bored cast-in-place pile with interior support is used for the Phoenix International Bookstore in Suzhou based on peripheral circumstance, geological conditions and excavation depth. Because of approaching the subway station and complex peripheral circumstance, the monitoring design is set up according to related rules. The monitoring items including deep horizontal displacement, decline in groundwater level and subway station displacement are analyzed. Two different lifting and subsidence techniques of three axes agitating pile can be prioritized for waterproof curtain of underground three layer engineering. Reduce in groundwater level in the first confined aquifer in a small region has little effect on the surrounding buildings. The results is useful for the regional foundation pit design. |
