附录AFire Simulation and Safety EvacuationOptimization of mountain ancient buildingGroups Based on BIM TechnologyYiping Wang,Liqiong Yang',Yan Zhong',Song Gu!707269027@qq.c0mCollege of Civil Engineering and Architecture,Southwest University of Science andTechnology,Mianyang,ChinaAbstractThis study aims to research the law of smoke spread and personnelevacuation when a fire occurs in a mountain ancient building group.First,theBIM model of one mountain ancient building groups in Sichuan Province wasestablished,and the fire spread trend of ancient buildings was analyzed based onfire simulation analysis.After the fire in the ancient buildings,the smoke firstdevelops upward from the fire source and then spreads vertically from high tolow.The simulation results show that the flue gas concentration is the mostcritical factor which affecting the available safe evacuation time.Based on theset fire scene,the personnel evacuation in this scene is simulated by Pathfinder.The results indicate the evacuation emergency channel is narrow and the densepalace area cannot meet the requirements of safe evacuation.By increasing thewidth of the passageway,it can effectively reduce the personnel density of the一1-congestion point.This study provides a basis for relevant departments toformulate intelligent personnel evacuation plan.Keywords Ancient Buildings,Fire Simulation,Evacuation Simulation,BIM-2-哈尔滨理工大学学士学位论文1 INTRODUCTIONSichuan has a profound historical and cultural heritage.There are manyancient buildings with local characteristics,mostly brick and wood structures.Most of the ancient buildings in Sichuan are based on the environment andintegrate the buildings into the natural environment,mostly distributed in thetranquil mountains of the environment.Ancient buildings are generally built onthe slope of the terrain.The courtyards are staggered,arranged in groups,andthe passages are tortuous.In the event of a fire,it is easy to cause "Burning ofthe linked camps",and due to the limited location of the building,the firefightercannot arrive in time,especially in the tourist rush season,there are manytourists and the evacuation is more complicated.Therefore,it is very importantto make a fire emergency evacuation plan.Scholars have carried out relevant research on the fire spreadcharacteristics of ancient buildings and emergency evacuation.JiangShiyong(2013)manalyzed the variation of firerelated parameters throughsimulation for the fire scene of typical ancient temples in Jiuhua Mountain.ShiLei(2012)P2took Yuelu Academy as the object,based on the analysis of the firespread trend,the evacuation models under different fire scenarios wereestablished based on Pathfinder,and the influence of the safety exit position onthe evacuation efficiency was analyzed.Zhang Lin(2013)Btook the ancientbuildings in the historical and cultural block of Sanfangqixiang as the object,analyzed the fire safety performance,and put forward the fire improvementmeasures through the evacuation simulati
