Abstract	Now, the standard about urban tunnel with roof openings is blank. The study establish the model of urban tunnel with roof openings, make the basic experiment research about ventilation effect of natural ventilation openings, which in two condition, piston wind and the coupling effect of piston wind and jet fan. The result of experiment indicate that as the increase of traffic flow, speed of vehicle, and as the decrease of distance with tunnel exit and roof openings, the air volume through roof openings is increasing. With the effect of fan between roof openings, all openings would become steady air-inlet or air-outlet.
