超深基坑的支护设计与施工研究

Research on Support Design and Construction of Ultra-Deep Foundation Pit

苏州“东方之门”项目的基坑是一个超大超深基坑,根据环境特点,其围护设计采用了复合型支护形式。在实施过程中,施工单位通过对设计方案及其危险源的分析,在施工中采用了众多针对性防范措施。经过精心组织,顺利地完成了该基坑施工,达到了经济性与安全性的高度统一。

The foundation pit of the "Gate of the Orient" in Suzhou is a super-large and deep foundation pit. According to the characteristics of the environment, the design of the foundation pit support adopts the composite support form. During the implementation process, through analysis of the design plan and the source of danger, a number of reasonable and targeted measures were adopted in the construction. After careful organization, the construction of the foundation pit was successfully completed, achieving a high unity of economy and safety.
