Research On Public Space Emergency Design Of A Branch Airport Terminal Under Major Public Health Emergencies

The frequent occurrence of all kinds of public health emergencies has had a painful impact on public health,life safety and social economy.The outbreak of COVID-19 at the end of 2019 has brought a heavy disaster to mankind and has had a profound impact on our way of life and philosophy.Regional airport terminal is the core node of civil air transport.In the face of public health emergencies,how to improve the safety of its public space from the architectural level and solve the problem of emergency design of such buildings has become an important topic worth further study in the current society.First of all,this thesis establishes a research framework based on the theory of public space and emergency design of regional airport terminals.The development history of domestic and foreign terminals was reviewed,and the limitations and new trends of terminal development in China under the normal epidemic prevention and control were summarized.On this basis,the basic characteristics of branch airport terminal are analyzed from three aspects: planning mode,function structure and process streamline.Secondly,through the method of field research,this thesis conducts in-depth research on the public space of a branch airport terminal,mainly focusing on the spatial planning and epidemic prevention facilities of the terminal,so as to explore the existing emergency problems under the background of the epidemic.In addition,deep learning technology and manual investigation method are used to carry out statistical analysis on passenger traffic characteristics and passenger behavior characteristics inside the terminal,and take this as the basis for the pedestrian parameter calibration of the subsequent simulation model.Thirdly,according to the research purpose,this thesis selects Anylogic simulation platform to build a regional airport terminal public space risk identification system composed of simulated physical environment model,passenger behavior process model and multi-agent infection model.Taking the research object as an example,this thesis builds a regional airport terminal public space simulation model.After reliability verification of the model,The case study of risk identification was carried out,and the simulation results such as the estimated number of infected people and the distribution of risk characteristic points were analyzed quantitatively.Finally,combining the qualitative analysis results obtained from the research and the quantitative analysis results obtained from the simulation,this thesis proposed the emergency design strategy for the public space of the branch airport terminal from the architectural level,and generated the optimized scheme combined with the research objects.Again,the Anylogic simulation platform was used to compare and verify the optimization before and after.The results show that the optimized scheme can better reduce the number of infected people and reduce the distribution of risk feature points,which indicates that the optimization strategy proposed in this thesis has certain effectiveness,in order to provide reference for the emergency design research of such buildings.
