双洞互补式通风在大别山隧道中的应用研究

针对大别山特长公路隧道左右线通风负荷不均衡的情况,提出双洞互补式通风系统设计理论和方法。即在左右隧道之间增设横向通风道,将两条隧道联系起来,用空气质量较好的隧道内新鲜空气去稀释空气质量较差隧道内的污浊空气,并使两条隧道内的空气质量均满足通风要求。在大别山隧道应用中可取消增设的通风斜井,大大降低土建费用和运营管理费用。

Application Research for the Complementary Ventilation of Dabie Mountains Tunnel

In order to solve the uneven ventilation loads of Dabie mountains,we proposed the design theory and formulas of a new-style ventilation called double holes complementary ventilation type.By increasing the transverse duct to connect each tunnel,we can use the air which has a good quality to dilute another tunnel＇s polluted air,then each tunnel＇s air quality can meet the ventilation requirement.By means of this new ventilation type,not only we can cancel the ventilation shaft,but also can reduce the initial construction cost and the subsequent operating expenses.
