摘要：In order to probe the panic psychology effect on the evacuation characteristics and evacuation efficiency under an emergency such as a fire in a railway tunnel, this paper uses a combination of theoretical derivation and 3D simulation technology to study personnel evacuation, investigates the psychological panic effect coefficient of the evacuation speed under various situations such as different numbers of personnel and structural parameters in emergency rescue evacuation facilities (emergency rescue stations, emergency exits, shelters) of railway tunnels to determine the range of influence factors of crowd evacuation speed under psychological panic. Studies show that: ①Considering the effects of psychological panic factors, the speed of evacuation should increase by about 1.25 to 1.49 times, with an average of about 1.37 times; ②The panic reduction factor for the crowd evacuation time at the emergency rescue station of the railway tunnel is 0.8 ~ 1, and the panic reduction factor for the crowd evacuation time at the emergency exit and refuge is 0.75 ~ 1.05.
