Analysis Of Influencing Factors Of Emergency Evacuation Of Vertical Ship Lift Chamber

As an efficient and low-cost navigable facility,the vertical ship lift plays an important role in the navigation of high dams in my country.Due to the characteristics of the semi-enclosed envelope structure,the horizontal evacuation time of passengers in the carrier compartment is affected by many factors.In order to improve the emergency evacuation efficiency of ship lifts,reduce passenger casualties,and ensure the safety of shipping in water conservancy hubs,this paper carries out the analysis of factors affecting the emergency passenger evacuation of ship lift cabins and simulation experiments,revealing the influence of relevant factors on the evacuation time.It is of great significance to ensure the safe operation of navigable buildings.Firstly,this study analyzes the impact of environmental factors on evacuation behavior,and describes the evacuation deck and exit width and other related parameters based on the circular evacuation path feature of the ship-lift cabin with four exits.Divide the normal speed of the influencing factors such as gender,age and number of passengers,discuss the psychological conditions of passenger’s panic and herd during emergency evacuation,and the influence of their behavior on the force during evacuation.Secondly,this article describes 12 routes for the evacuation of passengers in the carriage,and calculates the distance of each route.Analyze the three basic forces of the passenger’s own driving force,the passenger interaction force,and the force between the passenger and the obstacle,introduce the conformity coefficient and the panic coefficient to modify the driving force,define the field of view to modify the passenger and the passenger and the obstacle.The calculation method of the evacuation speed of passengers is proposed.Study the objective conditions of exports and blockage effects,establish an export selection function,and construct a time calculation model.Finally,take the Three Gorges ship lift carrier compartment as an example.According to its spatial structure,Anylogic is used to construct an emergency evacuation simulation environment,and the statistical characteristics of past standard ship passengers are used as the basic input conditions for the simulation.The simulation deck and exit width,number of passengers,Evacuation scenarios under different combinations of conditions such as age structure,baggage carried and herding coefficient,etc.,calculate the evacuation time,apply the control variable method,and reveal the law of the influence of related factors on the evacuation time.The horizontal evacuation time model constructed in the thesis can provide references for other types of ship lift evacuation research,and has a certain guiding significance for improving the related research of my country’s ship lift evacuation strategy.
