Abstract：Sudden earthquakes pose enormous risks,often accompanied by secondary disasters such as fires.It is particularly important to reasonably organize the evacuation of people,effectively reduce congestion and stampede accidents,and improve the evacuation efficiency of people in response to the disaster when the fire disaster breaks out.The Pathfinder evacuation software was used to simulate the emergency evacuation of the personnel in an office building in China when an earthquake-induced fire occurred.The evacuation scenario under different parameter settings such as personnel behavior,personnel speed,and personnel proportion was studied by using the control variable method.The results indicate that the personnel speed and personnel proportion are the major factors affecting personnel evacuation.Increasing the personnel speed or reducing the proportion of the elderly will shorten the evacuation time,but increasing the personnel speed or changing the personnel proportion to a certain limit will gradually weaken the influence.The research put forward the delay evacuation strategy during fire disasters,which has a good reference value for optimizing the personnel escape behavior and standardizing the emergency evacuation management in densely populated areas.
