Analysis on Surrounding Rock Deformation Law in Highway Tunnel Construction Process
The deformation of tunnel surrounding rock under adverse geological conditions has always been a key and difficult point in the research of related fields.Taking a highway tunnel excavation project as an example,this paper analyzes the deformation law of surrounding rock under the working conditions of different soil-rock interface positions during tunnel construction by means of numerical simulation.The results show that the surface settlement curve is in a"basin"shape,and the peak settlement appears at the middle line of the tunnel.Under the working conditions of different soil-rock interface positions,the distribution law of surface settlement is basically the same,and the main difference is numerical difference.
