Commercial Complex Indoor Pedestrian Street Evacuation Optimization Strategy Based On SIMULEX Simulation

In recent years,more and more commercial complexes have been built,and the related research has become a hot topic.As an important carrier of urban activities and spiritual culture,the construction of commercial complexes often plays an important role in the development of the nearby area.Increasingly complex formats and increasingly large scale,bring a lot of problems for fire evacuation.In practice,the fire safety performance of the pedestrian street is often strengthened,and it is used as a "quasi-safe area" to solve the problem of breaking regulation laws such as the long evacuation distance.However,indoor pedestrian streets in actual use do not necessarily ensure safety.Evacuating to the pedestrian area,does not mean really escaping to the outside.People here may not be able to get a very effective further evacuation.Based on the above questions,aiming at the most characteristic indoor pedestrian streets of the commercial complex,this study starts from the large fire zone of the indoor pedestrian streets and surrounding commercial space,and studies the pedestrian streets,the small halls and the safe passages in the whole area.And the relevant evacuation and optimization design strategy are obtained.First,qualitatively,the related concepts,principles and methods are analyzed,and the relevant basic contents of the commercial pedestrian street are studied,and the evacuation and simulation are discussed.Then,through the refinement of the basic form of the indoor pedestrian street,the basic experimental model is established and the simulated boundary conditions are set.Next,the research process adopts the method of qualitative and quantitative combination,through the method of controlling variables,for the relevant factors to design the comparative experiment,using SIMULEX software for evacuation simulation.By observing,recording and analyzing the evacuation experiments,the corresponding laws are found.By summarizing and analyzing the results,this paper puts forward the relevant evacuation and optimization strategy for the commercial pedestrian street.The conclusion of the simulation experiment can provide the basis for the optimization of the design of the commercial pedestrian street and the supplement of the relevant norms and the in-depth study of the related fields.To ensure the safety of personnel life,further research of the subject is important.
