| Abstract: | Ventilation of extra-long tunnel is now the challenge in tunnel construction. In order to understand the main influence factors of long tunnel construction ventilation,this paper,based on the engineering of the Bibanpo tunnel of Shanghai to Kunming high speed railway,analyzes the monitoring data related to the ventilation system and air quality in and outside the tunnel,and summarizes the main factors influencing construction ventilation air quality,such as the temperature difference in and outside the tunnel,ventilation design,construction organization and excavation method,which may serve as references for the construction ventilation and optimization of similar extra-long tunnels. |
