摘　　要：对于以钻爆法为主要掘进方式的大断面公路隧道,合理的通风系统是保障隧道施工进度、工人作业安全的前提,因此为将爆破产生的污染物在短时间内排出洞室,需选择合理的通风方式及通风设备选型。以梁王山隧道斜井工区为工程依托,基于施工规划与通风设计理论,将通风划分为三阶段,根据不同阶段的施工线路特征,简要阐述通风过程的重难点,最终对各阶段通风方案进行设计,并提出了通风系统优化措施,为类似隧道工程的通风设计提供参考。In the large cross-section road tunnels with drilling and blasting method as the primary excavation technique,a well-designed ventilation system is essential for ensuring construction progress and worker safety.To quickly remove the pollutants generated by blasting from the tunnel,it is necessary to choose a reasonable ventilation method and equipment.Using the inclined shaft section of the Liangwangshan Tunnel as a case study,this paper,based on the theory of construction planning and ventilation design,divides the ventilation into three stages.According to the characteristics of the construction line in different phases,it briefly describes the challenges and key points of the ventilation process.Finally,ventilation schemes for each stage are designed,and optimization measures for the ventilation system are proposed to serve as a reference for similar tunnel projects.
