Based on the Treatment Technology of Shallow Buried Tunnel
With the rapid development of highway engineering construction in China,the safety construction of tunnels is becoming more and more important,especially the construction safety of shallow buried tunnels.Taking the Hanbang No.1 Tunnel of Yuewei Port Link Highway as an example,this paper analyzes the causes of tunnel collapse in depth,mainly including geological conditions,rock strata stress,surrounding rock stability and rainwater infiltration.In view of the collapse situation,the project department has taken a number of emergency treatment and treatment measures,such as strengthening monitoring and measurement,grouting reinforcement,backfilling and counterpressure,etc.,which successfully controlled the impact range of the collapse and ensured the safety and quality of construction.This paper elaborates the process and effect of collapse treatment,in order to provide a valuable reference for similar tunnel engineering.
