Research on Construction Control Technology of Soil Pressure Equilibrium Shield Tunneling in Geological Fracture Site
In this paper,the basic situation and geological conditions of a subway tunnel project with geological fracture zone are briefly intro-duced,and the technical difficulties and risks of shield construction are analyzed.In this study of shield construction technology and measures in the geological fracture zone,it is suggested that some technical measures should be taken in advance,such as geological supplementary pros-pecting,increasing monitoring frequency and improving residue to prevent jamming,before entering the site of the geological fracture zone.The data analysis and experience summary combined with the control effect of this research can provide some reference for the construction control and management of similar sites.
