文章基于某隧道工程实例，通过模型试验方法研究了通风井型隧道处于交通阻滞时通风井的通风效果。研究结果表明：当隧道仅凭借车辆低速运动产生的交通风进行自然通风时，通风井处于周期性进、排风转换状态且通风量较低；当采用射流风机与交通风相结合使通风井处于常排风状态时，矩形通风井的排风量随横截面当量直径增大而增大，通风井排风量随通风井倾斜角度减小而增大。

Based on a tunnel practice, the ven tilation effect of the shaft during traffic clogging in a tunnel with ventilation shaft is studied through a model test. The research results show that ventilation shaft presents a character of cyclical transition between air intake and air exhaust with small air quantities when natural ventilation due to low speed movement of vehicles is used;and air exhaust rate of rectangular shaft increases with the increase of cross-section equivalent diameter while air exhaust rate increases with the decrease of slope angle of ventilation shaftwhen a combination of jet fan and traffic induced air is used to keep a constant state of air exhaust.
