邻近地铁隧道的深基坑开挖技术研究

Study on Deep Foundation Pit Excavation Technology Adjacent to Subway Tunnels

城市轨道交通工程中的地下隧道与众多深基坑存在空间上的邻近关系,时间上的施工先后关系,在这种复杂的时空关系下,一旦开挖技术的操作缺乏专业性,就会诱发严重的质量风险与安全事故。基于此,本文结合某深基坑开挖工程的实际情况,简要分析了邻近地铁隧道的深基坑开挖施工要点后,重点阐述了开挖技术的应用方法,并提出控制施工风险的有效措施,旨在提高深基坑开挖施工质量和效率,以期为从业人员提供参考和借鉴。

There is a spatial proximity relationship between the underground tunnel and many deep foundation pits in urban rail transit engineering,and the construction sequence relationship in time is in this complex spatio-temporal relationship.Once the operation of excavation technology lacks professionalism,it will induce serious quality risks and safety accidents.Based on this,this paper briefly analyzes the key points of deep foundation pit excavation near the subway tunnel in combination with the actual situation of a deep foundation pit excavation project,focuses on the application method of excavation technology,and puts forward effective measures to control the construction risk,aiming to improve the quality and efficiency of deep foundation pit excavation construction,in order to provide reference and reference for practitioners.
