Abstract
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.
Highlights
The railway tunnel is dark and long
Under the influence of panic psychology, the speed of evacuation of people will increase to varying degrees
A certain degree of individual evacuation speed may increase the efficiency of crowd evacuation
Summary
The railway tunnel is dark and long. Once an emergency such as a fire occurs in the railway tunnel, people need to get out of the train and evacuate. Under the influence of panic psychology, the speed of evacuation of people will increase to varying degrees. A certain degree of individual evacuation speed may increase the efficiency of crowd evacuation. There is a certain blindness in the choice of personnel, which leads to a decrease in evacuation efficiency; Farkas I J, et al 6 studied the parameters such as the time and speed of evacuation, and clarified that panic psychology can both promote and hinder the evacuation efficiency; Chen Changkun et al 7 studied the influence of panic mood on the behavior of crowds in evacuation and its regularity. For the evacuation of people in a railway tunnel fire mode, it is even more necessary to study the factors of panic according to factors such as structural characteristics, evacuation routes, and evacuation numbers, determine the panic reduction factor suitable for the speed of crowd evacuation in a railway tunnel emergency (fire)
