摘　　要：雀儿山隧道为双向行车特长公路隧道,受自然风影响,不同自然风速下风机的控制方法不同。采用网络通风的计算方法,对不同自然风风速工况下,双向行车特长隧道平导压入式通风进行计算,得到具体的风机控制方案。研究结果表明,采用平导压入式通风的雀儿山隧道,由于自然风压的存在,需在主隧道中设置射流风机;为使隧道内的风流按需分配,主隧道内射流风机的工作方向与自然风方向相反;自然风速越大,主隧道内需要开启的射流风机台数越多。The Queershan tunnel was a two-way traffic super long highway tunnel,affected by the natural wind,the control methods of fans were different under different natural wind speeds,through using the calculation method of network ventilation,calculated the horizontal guiding and pressing ventilation of two-way traffic super long tunnel under different natural wind speeds,obtained specific fan control scheme,the research results showed,the Queershan tunnel with horizontal guiding and pressing ventilation,due to the existence of natural wind pressure,jet fans need to be installed in the main tunnel,in order to distribute the air flow in the tunnel according to the demand,the working direction of jet fans in the main tunnel was opposite to that of natural wind,the larger of natural wind speed,the more jet fans need to be opened in the main tunnel.
