摘要
中国丝绸城工程基坑深14.05~16.6m,周边建筑物众多,环境保护要求高。详细介绍了该基坑工程设计的过程,包括逆作法的基坑支护设计方案、二墙合一的地下连续墙设计、水平和竖向支撑体系的设计。实践表明,该工程采用逆作法的施工工艺,同时结合信息化施工,确保了周边环境的安全。通过实践及对监测结果的分析,得出了一些有价值的结论。
The top-down constructing method was used in a 14.05 - 16.6m deep foundation pit engineering in Hangzhou. The deep pit is surrounded by many buildings and the requirements for protection of surrounding environment are quite strict. The design course of foundation pit was introduced. The top-down method was used in the design scheme including the design of diaphragm wall, the horizontal and vertical system in the foundation pit. It is shown that the top-down method associated with monitoring technology can ensure the safety of the surrounding environment. Some useful conclusions are obtained through the analysis of measured results.
