Construction and Management Control of Tunnel Construction Risk Model
In view of the complex geological conditions,especially the karst cave and karst bridge,encountered in the tunnel construction of Liuwu Railway Section 6,the risk assessment and construction scheme optimization are carried out systematically.Based on the comprehensive application of geological exploration,finite element analysis and dynamic monitoring technology,a construction model is established and a series of effective construction measures are put forward,such as advance small pipe grouting,segmental excavation and support synchronization.The implementation of these measures effectively improves the safety and stability of tunnel construction and reduces the construction risk caused by complex geological conditions.The research results provide important theoretical support and practical experience for similar projects.In the future,with the development of intelligent monitoring technology,the safety management level of tunnel construction will be further enhanced,which provides more powerful guarantee for tunnel construction under complex geological conditions.
