针对两河特长公路隧道左右线通风负荷差异较大的情况,采用双洞互补式通风设计理论及方法,对两河隧道通风系统进行优化设计。采用横向通风道使上下行隧道形成整体通风网络,以下坡隧道内污染物浓度较低的空气去稀释上坡隧道中污染严重的空气,使2条隧道内的通风均满足规范要求。互补式通风方式充分利用隧道内部空间与下坡隧道的富裕通风能力,取消通风竖井,使通风系统整体经济效益得到显著提高。
針對兩河特長公路隧道左右線通風負荷差異較大的情況,採用雙洞互補式通風設計理論及方法,對兩河隧道通風繫統進行優化設計。採用橫嚮通風道使上下行隧道形成整體通風網絡,以下坡隧道內汙染物濃度較低的空氣去稀釋上坡隧道中汙染嚴重的空氣,使2條隧道內的通風均滿足規範要求。互補式通風方式充分利用隧道內部空間與下坡隧道的富裕通風能力,取消通風豎井,使通風繫統整體經濟效益得到顯著提高。

In Allison to big difference between left and right line ventilation loads in Lianghe Extralong Tunnel, this paper adopts double-hole complementary ventilation design theory and method to optimize design of ventilation system in Lianghe Tunnel. The paper employs transverse airways to make uphill and downhill tunnels form integral ventilation grid with the air at low density of pollutants in downhill tunnel to dilute the air with serious pollution in uphill tunnel, enabling ventilation in both tunnels to satisfy the requirements of specification. The complementary ventilation takes full advantage of internal space in tunnel and redundant ventilation capacity in downhill tunnel and cancels ventilating shaft so as to improve integral economic benefits of ventilation system remarkably.
