Research on the Evacuation Efficiency of People in Subway Stations Under Flooding Scenarios
In order to improve the evacuation efficiency of people in the subway station under the flooding backflow sit-uation and develop a reasonable emergency plan for subway evacuation,this paper builds a subway station under the flooding backflow scenario based on the Anylogic simulation software,taking the Jinsha Lake station of Hangzhou sub-way as an example to study the evacuation efficiency of subway crowd under different water depths,the results show that the water depth and the number of entrances and exits can have an impact on the safety evacuation efficiency of people.Setting the inflow barrier can save more than 18%of evacuation time,and when the water depth in the station exceeds 20 cm,the evacuation time will exceed 6 minutes due to the slow walking speed of pedestrians,which cannot meet the safety evacuation requirements.
