Study of Tunnel Leakage Current Situation and Lining Structural Safety of Operating Expressway Tunnels

Abstract:

Based on the comprehensive data collection of the status of operating highway tunnels’ leakage diseases in Chongqing area, this essay conducted statistical analysis on the leakage state of the typical tunnel with leakage disease. According to statistical rule, this essay builds up numerical simulation model and applies Finite difference method to study the security of the lining when the cracks appear in different parts and under the conditions with or without water. The results of this research can be applied to the control of the leakage disease of the tunnel in Chongqing area and maintaining in operating, and this can also provide a reference to the calculation of lining security and bearing capacity for these tunnels.
