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.
