| Abstract: | Numerous tunnel fires occurring in China and foreign countries demonstrate that fires can severely destroy the lining structure and that the fire-resistant performance of the lining is of great importance.With Jiaozhou Bay tunnel in Qingdao,China as an example,the numerical simulation of the temperature field of the tunnel lining under high temperature in case of fire is presented,the rule of the temperature distribution along the lining thickness under high temperature in case of fire is studied and a seri... |
