特长公路隧道独头掘进施工通风组织研究

摘要

以广东省博深高速公路石鼓隧道、水涧山隧道为依托，探讨3车道大断面特长公路隧道独头掘进条件下的施工通风组织技术。从长距离独头掘进施工作业环境的卫生标准、施工通风方式选择、施工通风计算、施工通风方案等方面，系统搭建我国特长公路隧道独头掘进施工通风组织的核心技术框架，对我国隧道工程建设技术水平和理念的提高具有特殊意义。%On the basis of Shigu Tunnel and Shuijianshan Tunnel on Boluo-Shenzhen Expressway in Guangdong, this paper discusses techniques for ventilation organization in construction of 3-lane large-section extra long tunnels under the blind heading condition. The paper systematically establishes the core technical framework of ventilation organization in blind heading construction of extra long highway tunnels in China in view of sanitary standards, selection of ventilation modes in construction, calculation of ventilation in construction and ventilation schemes in construction, etc. in operating environment of long-distance blind heading construction.
