Abstract: In order to obtain the law of the influence of group panic on passengers’non- adaptive evacuation behavior during a sudden subway fire, passengers of Xi'an subway were taken as the research object, and the group panic scale was designed. The group panic scale was divided into four dimensions: fire information recognition ability, group convergence effect, stress environment stimulation and fire accident severity. Panic mood was introduced as an intermediary variable. Assumptions was presented about the effect of group panic on non- adaptive evacuation behavior, theoretical model was constructed by SEM, and then the scale data was used to empirically test the model. Finally, the model results was derived and explained. The main conclusions are as follows: the stress environment stimulation and the fire accident severity are the main factors leading to the non- adaptive evacuation behavior of passengers; The group convergence effect and the fire information recognition ability also affect non-adaptive evacuation behavior.

Key words: subway fire, group panic, non- adaptive evacuation behavior, SEM model
