Abstract
This study aims to research the law of smoke spread and personnel evacuation when a fire occurs in a mountain ancient building group. First, the BIM model of one mountain ancient building groups in Sichuan Province was established, and the fire spread trend of ancient buildings was analyzed based on fire simulation analysis. After the fire in the ancient buildings, the smoke first develops upward from the fire source and then spreads vertically from high to low. The simulation results show that the flue gas concentration is the most critical factor which affecting the available safe evacuation time. Based on the set fire scene, the personnel evacuation in this scene is simulated by Pathfinder. The results indicate the evacuation emergency channel is narrow and the dense palace area cannot meet the requirements of safe evacuation. By increasing the width of the passageway, it can effectively reduce the personnel density of the congestion point. This study provides a basis for relevant departments to formulate intelligent personnel evacuation plan.
