Simulation And Optimization Of Emergency Rescue Plan For Fire Accident At Civil Airport Terminal

With the rapid development of civil aviation,civil aviation carrying the transportation pressure increased year by year.Terminal as an important part of the transportation infrastructure,space complex,personnel flow huge,huge accident consequences,how to ensure the safe and effective operation is the key point that the present stage needs to consider.Fire is a key object in tall buildings.Combined with the characteristics of personnel concentration,how to take effective emergency rescue plan to control the occurrence and development of fire is very important for the safety of the terminal,and the fire emergency rescue plan is a special emergency rescue plan for the airport emergency plan.In order to prevent and control fire accidents,the special emergency rescue plan was established.In addition,due to the rapid development of computers,the use of simulation software is increasing.The research on building fire is becoming more and more perfect.The application of dynamic simulation of fire by simulation software is increasing.In this paper,we used Building Information Modeling method and Pyrosim fire simulation software to simulate the scene of the fire accident and conduct evacuation simulation records.After analyzing the simulation results,we gave the optimization of the emergency rescue plan for the airport terminal.The specific research work is as follows:(1)The use of BIM architectural design software and a large domestic airport waiting hall established a 3D visualization model for the information model.We determined the material of the building objects in the waiting hall,and the related factors of the combustion reaction are added in detail to ensure the high degree simulation of the model.(2)A good building model was introduced into the fire simulation software Pyrosim,and various parameters of the fire scene were set up,and all the fire simulation results were obtained and recorded through the operation simulation process.(3)The evacuation function of FDS+EVAC personnel in the fire simulation software was used to set up the evacuation parameters,including the movement speed,the reaction time,the influence of the moving friction force,the personnel's familiarity with the evacuation exit and other related parameters,and the evacuation simulation operation was carried out and the results are recorded.(4)Use the optimization algorithm to find the terminal building fire evacuation plan for emergency rescue personnel and the optimal fire control scheme,simulation parameters set above the scene after the combination.compared with the original fire rescue plan,we got the key factors of fire control and evacuation of personnel,The influence of temperature field,smoke field and evacuation port on emergency rescue was summarized,and suggestions for emergency rescue of civil airport terminal were put forward.
