为解决2车道公路隧道射流风机的空间布局优化问题，依托明堂山隧道工程，采用以往公路隧道射流风机通风效果数值模拟研究中不同的边界条件，将隧道出入口边界条件均设为大气压强，并不预先给定隧道入口风速大小。对影响射流风机升压力大小的因素，如风机纵向间距、风机布置高度、风机横向间距展开讨论，得到： 风机应设在距建筑限界15～30 cm高度处；风机横向净距应设为1.5～2倍风机直径；风机纵向间距应设在150 m以上。明堂山隧道实际风机布置方式所采用的参数均在优化结果范围内，按隧道实际长度及设计射流风机台数建模，模拟结果表明风机在进行优化布局后，隧道通风效果能够达到设计要求。

The jet ventilation of Mingtangshan Twolane Road Tunnel is numerically simulated so as to optimize the spatial layout of ventilation fans; and then the factors for the pressure rise of ventilation fan, i.e. longitudinal distance among fans, setting height of fan and transverse distance among fans, are discussed. The authors suggest that the jet fans should be installed at the position higher than building boundary about 15-30 cm； the transverse distance among fans should be 1.5-2 times fan diameter； and the longitudinal distance among fans should be larger than 150 m. The computational fluid dynamics (CFD) simulation results show that the jet ventilation fan after optimization can achieve good effect.
