Seismic Damage Rules and Seismic Risk of Tunnel Portals Based on Fuzzy Comprehensive Evaluation Method
A fuzzy comprehensive evaluation method was put forward to study the seismic risk of tunnel portals. Through collecting and analyzing information of seismic damage of the tunnel portals after Wenchuan Earthquake, the main influence factors of tunnel damage and its function law were summarized. The risk factors' weight and the membership degree to the risk level were calculated respectively by AHP and trapezoidal membership function and semantic subordinate function. Seismic risk level of tunnel portals was concluded through fuzzy transformation principle and weighted average method. At last, a case was done on a built tunnel by fuzzy comprehensive evaluation. The conclusion could be used to take corresponding measures to reduce seismic risk.
