摘要
针对某位于复杂周边环境情况下超大超深基坑围护结构方案进行分析,通过对中心岛法和全盖挖逆作法方案进行比选,从结构安全性、经济性、工期等多方面分析,提出中心岛法和全盖挖逆作法均可应用于超宽超深基坑,在基坑工程施工中可创造较好的经济效益与社会效益。
Aiming at some complicated surrounding environment,the paper analyzes the ultra-deep foundation pit＇s surrounding structure scheme, by comparing the mid-island method and the cover-excavation reverse method,indicates from the structural safety,the economy and engineering period,and points out that the mid-island and the cover-excavation reverse method can be applied the ultra-deep foundation pit,and they can create better economic and social benefits in the foundation pit project.
