摘要
特长隧道通风是目前隧道工程建设中的难点,为分析影响带平导特长隧道施工通风的主要因素及其规律,以沪昆客运专线壁板坡特长隧道为工程背景,分析隧道施工时的通风系统和洞内外空气质量的监测数据,并结合目前对隧道施工通风影响因素的研究成果,总结影响特长隧道施工通风洞内空气质量的主要因素及其特征,包括洞内外的温度差、通风方案、施工组织和掘进方法,以达到合理组织隧道施工与优化通风的目的,为类似特长隧道的施工通风及其优化提供参考依据。
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.
