复杂条件下地下工程深基坑支护施工技术分析

Analysis on Deep Foundation Pit Support Construction Technology in Underground Engineering under Complex Condition

文章基于复杂条件下的地下工程,对深基坑支护施工技术进行深入的分析。具体探讨深基坑支护施工技术中的止水帷幕施工、支护结构施工、基坑开挖施工、降水管井设计及施工、轻型井点设计及施工,通过对多种支护结构的分析,结合实际工程案例,详细阐述在复杂条件下如何合理选取支护结构、优化施工方案,旨在为类似工程提供有益的参考,促进地下工程深基坑支护施工技术的进一步发展。

Based on the underground engineering under complex conditions,this paper makes an in-depth analysis of deep foundation pit support construction technology.Deep foundation pit support construction technologies such as water-stop curtain construction,supporting structure construction,foundation pit excavation construction,dewatering tube well design and construction,light well point design and construction are specifically discussed.Through the analysis of various supporting structures,combined with practical engineering cases,it elaborates how to reasonably select the supporting structure and optimize the construction scheme under complex conditions,in order to provide useful reference for similar engineering and promote the further development of the deep foundation pit support construction technology in underground engineering.
