Optimization of Super Large Deep Foundation Excavation Supporting Scheme by Using Space Effect

利用空间效应对超大型深基坑支护方案进行优化,将大跨度边坡进行分区设计,对薄弱区域设置支护加强带,达到增强支护稳定性及降低工程造价的效果。将该优化设计思路运用到典型超大型深基坑项目———望京SOHO,取得良好效果。

With the constantly demands of complex large deep foundation excavation engineering,the requirements of design,calculation,as well as the excavation and supporting technology during construction are urgently needed. This paper gives the analysis of Wangjing SOHO project to strengthen the support stability and reduce the project cost by using the space effect of super large deep foundation excavation support scheme in optimizing.
