Abstract
The acquisition of elastic resistance coefficient is crucial for the design of shallow hydraulic tunnel. In this paper, the resistance coefficient of the tunnel in the test section of the South Main Canal Project is monitored and analyzed. Considering the actual load mode of the tunnel lining, the load value acting on the lining is measured by the measurement instrument on the spot, and the elastic resistance acting on the tunnel lining is obtained. The elastic resistance coefficient acting on the tunnel lining is obtained through the deformation around the tunnel on the measuring side. The research conclusions and methods can provide reference for the support design of shallow hydraulic tunnel in loose soil layer.
