摘要:行业中对于超大深基坑支护的施工与组织相对较困难,而加上周边环境复杂及地处一线城市中心区域就更需精心合理科学组织施工.本文从施工角度对临铁、临湖、遇泄洪暗涵超大深基坑施工进行分析,对前期临近地铁与场内泄洪暗涵的处理进行简述,并对比几种支护与土方施工方案进行技术分析,综合多方面因素考虑择选最优施工技术方案,对于类似项目有一定的借鉴及参考价值.Abstract: The construction and organization of super deep foundation pit support in the industry are relatively dificuli, and couplelwith the complex surrounding environment and being located in the central area of first tier cities, it is even more necessary to carefully andscientifically organize construction.This article analyzes the construction of super dep foundation pits near railways， lakes,and flooddischarge culverts from a construction perspective. Ilt briefly describes the treatment of nearly subways and flood dischare culverts in theearly stage, and compares several support and earthwork construction schemes for technical analysis.Taking into account muliple factorsthe optimal construction technology scheme is selected, which has certain reference value and reference value for similar projeets.
