Construction Technology of Advanced Large Pipe Roof for Subsurface Tunnel Excavation in Fault Fracture Zone
Underground engineering located in fault fracture zone usually faces the security threat brought by complex geological environment,which brings severe technical challenges to engineering construction.Based on the tunnel excavation project of Jinan Rail Transit Line 4,a large pipe shed is built along the longitudinal arch of the tunnel to strengthen the strata before the tunnel.This technology is flexible under complex geological conditions,effectively supporting the soil around the tunnel and reducing the risk of surface subsidence.On the basis of practical engineering cases,the advantages of construction technology of advanced large pipe shed are expounded in detail,and key construction parameters and methods are provided.
