Research on Fire Safety of Inserted Bar Glue of Roof Spacer in Tunnel

摘要：

Cangling mountain highway tunnel adopts the longitudinal ventilation by the vertical shaft and roof spacer. The roof spacer and the existed secondary lining are connected by planting reinforcing bar. In this paper the temperature field in tunnel inner space in different fire scenario is computed by FDS. The environment temperature of roof spacer and secondary lining was used as boundary condition to compute the temperature variation curve at the points of planting reinforcing bar by ANSYS. At last researched the safety performance of the inserted bar glue under high temperature according with the test report of performance of planting reinforcing bar at high temperature.
