超大面积复杂因素影响下深基坑分阶段实施的设计与施工

Design and Construction for Deep Foundation Excavation Constructed by Multi-stage Under Influence of the Extra Large Area with Complicated Factors

多种复杂因素的制约和影响下,设计和施工、技术和管理的协同推进,是摆在项目建设者面前的难题。以铁路杭州东站站房项目为例,对超大面积复杂因素影响下深基坑分阶段实施的设计方案与施工组织进行分析。监测数据反映,该基坑施工过程中,支护体系安全稳定。

It is a hard question for designers that how to combine design, construction, technique and management together and push them forward cooperatively under restriction and impact of various and complicated factors. Based on the project of station buildings of Hangzhou East Railway Station, this paper analyzed the design and constructional organization of deep foundation excavation, which is constructed in multi-stage. It was showed by monitoring data that the supporting system was stable and safe during construction.
