[0002] In existing life, due to the increase of traffic pressure, excavating tunnels and constructing urban subways have become an important way to relieve traffic pressure. The concealment of tunnels and urban subways is relatively large, and the geological conditions during construction are complex, and the potential accident risks cannot be predicted. , and for the sudden accidents of tunnels and subways, the main manifestations are the collapse of the vault and the water and mud on the side wall. There are many methods to control the settlement of the tunnel vault. At present, in tunnel construction, the problem of tunnel roof subsidence is common. , the subsidence of the vault in the tunnel may cause major safety risks or accidents in the tunnel and surrounding construction facilities
At present, the method of detecting settlement of tunnels mainly adopts manual detection of total station. However, the detection of total station requires manual point-by-point detection, which is time-consuming and labor-intensive, and cannot be detected in real time. At the same time, the detection accuracy is related to the operation of the staff. , resulting in larger monitoring errors and lower monitoring accuracy
