摘要：
Due to the limited space, the lateral pattern to control tunnel fire smoke spread is usually used by double-decked tunnel. There is a smoke exhaust dust in one side, and an exit passageway in the other. PDS is adopted in this article to discuss the lateral ventilation changes caused by different smoke vent area, number, and spacing. According to the research, lift the lateral smoke exhaust system in the condition of no longitudinal wind, the area, the number and the spacing of smoke vent obviously impact the spread of fire smoke only in the beginning of the fire.
