| 摘 要： | 依托乐红特长隧道工程，介绍了工程概况、需风量计算、通风方案论证。基于全寿命周期成本分析，推荐采用分段纵向式通风方式:右线采用单斜井两区段通风，左线采用两斜井三区段通风，左、右线均为三区段排烟，同时，根据近、远期交通量不同，制定了相应的通风系统运营策略，最大限度地提升了通风井通风效率，并降低了隧道运营费用。

Study on Ventilation System Design and Operation Optimization of Lehong Extra-long Tunnel |
| |
| Abstract: | In relation to the Lehong extra-long tunnel project, the project profile, the calculation of the required air volume and the demonstration of the ventilation scheme are introduced. Based on the life-cycle cost analysis, it is recommended to adopt sectional longitudinal ventilation: the right line adopts two sections of single inclined well for ventilation, the left line adopts three sections of two inclined wells for ventilation, and both the left and right lines adopt three sections for smoke exhaust. At the same time, according to the near- and long-term traffic volume, the corresponding ventilation system operation strategy is formulated to maximize the ventilation efficiency of the ventilation shaft and reduce the operating cost of the tunnel. |
