| A goal of safety evacuation design is to protect people in a state of emergency. Recent years, a lot of scholars in and out of China research the crowd movement rules and evacuation dynamics. But people pay more attention to that if the safety evacuation design can protect people in any fire scenes.This paper researches on the influence of fire position to safety evacuation. The result of study can provide a theoretical reference for safety evacuation design, and offer a scientific and rational method of building fire safety assessment. This paper analyses the state of evacuation in any fire scenes, and shows the extent of crowd jam in an evacuation cell.This paper pays attention to study some typical positions of fire taking place, and establishes a safety evacuation model considering the change of fire position to calculate the time of evacuation movement, then uses a practical example to quantitative analyses the influence of fire position to safety evacuation.The result of study shows fire position can influence the extent of crowd jam of evacuation cell, then the extent of crowd jam effect the time of evacuation movement. So fire position influence the safety evacuation time of a building as well. |
