Analysis and Field Test about Operation Ventilation Effect of Dabieshan Highway Tunnel

摘要

Twin tubes complementary ventilation technology was applied in Dabieshan highway tunnel for the first time in domestic. Based on test of the amount of carbon monoxide, smoke concentration and wind velocity, and analysis of the data, it is concluded that the twin tubes complementary ventilation technology is workable and reliable. In addition, the results provide the reference for the ventilation monitoring of Dabieshan tunnel and also for the technical guidance of ventilation mode in the later similar engineering design.
