Abstract: In order to study the interporosity flow problem in different forms of highway tunnel, as the speed of tunnel ventilation and the tunnel spacing for variables, simulate the interporosity flow issue of the double-hole tunnel, the single-hole continuous tunnel and the double-hole continuous tunnel. According the results of simulation, in the perspective of free jet flow, analysis and illustrates the interporosity flow characteristic of the three types tunnel, also the reasons of the pollutant distribution.
