Construction Technology of Underground Station Guide Tunnel Excavation
Combined with concrete engineering examples,this paper studies and discusses the implementation plan of guide tunnel excavation in subway underground stations in detail,focusing on the main points of the tun-nel excavation in subway underground stations,such as positive hole,large arc buckle arch,shotcrete,etc,the set-tlement test results show that the construction technology proposed in this paper can improve the design,con-struction and management level of subway engineering,make the arch settlement within a controllable range,and the construction in the tunnel meets the design requirements,providing technical support and guarantee for the sustainable development of urban subway traffic,and providing a certain reference for the excavation of guide tunnels in underground subway stations.
