Pre-Stressed Reinforcement and Security Analysis of Tunnel Lining with Dislocation and Cracks
Security of secondary lining is of utmost importance to tunnel engineering quality as the main bearing structure and the last water-prevent line for rock types I, II, III. Tunnel lining with dislocation and cracks is one of the most serious defects to secondary lining. Based on the case of Goujiagou tunnel, the potential threat is listed. The pre-stressed regulation scheme is designed, and the parameters are determined. The loose surrounding rock pressure on lining is calculated by P's theory. Based on the results, the numerical simulation model is build by means of FES code ANSYS; and the internal pressure before and after the reinforcement is analyzed. According to the above-mentioned research results, this paper calculated the safety factor, and checked the structure strength. Research results indicate that the regulation design is feasible and the pre-stressed parameters are appropriate. The results will provide reference to design for dislocation and cracks of tunnel lining.
