Fire accidents often lead to tremendous losses and smoke has been reported to be the main cause of these heavy casualties. Accordingly, smoke movement can influence escape and smoke confinement is particular significant. Fire Dynamics Simulator software (FDS) was utilized to carry out complementary full scale numerical simulations of fire accident in a subway station. Different measure of smoke prevention and exhaust were adopted and the difference of smoke confinement among the measure was compared. According to the smoke temperature, hung wall had a good role during early stage of fire accident. However, the performance became worse with smoke accumulation. If the hung wall were adopted, smoke was exhausted from basement 2 and air was supplied into the basement 1 at the same time, the efficacy of smoke confinement was the best. The mechanical exhaust rate had obvious implications for the smoke diffusion.
