Embodiment Construction

[0029] Because it may cause danger, the safety of building crowd evacuation cannot be obtained through real experiments, and simulation provides a safe and reliable method to test the safety of building evacuation. The simulation method provided by the invention can truly reflect the main characteristics of crowd evacuation in an emergency state, and effectively verify the evacuation safety of buildings. The invention provides an effective inspection method for the structural design safety of buildings.

[0030] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0031] mesh simulation

[0032] The social force involves the calculation of up to 6 forces, and the calculation of each force takes a lot of time. Take the psychological force of the wall on people as an example. When calculating, it is necessary to find out a...

Abstract

The invention discloses a building disaster evacuation simulation method based on an evacuation object social force evolution game model, which comprises the following steps: establishing an evacuation object social force model; Based on game theory, dividing the behavior of people at the exit into two kinds: cooperative behavior and competitive behavior, then, establishimg an evolutionary game model based on evacuation object social force model, and reproducing the cooperative and competitive behaviors between people by cellular automata, obtaining and saving the resultant force of social forces received by all evacuated objects according to the received related parameters, obtaining a time step by utilizing the maximum resultant force value therein, and determining the expected speed ofthe evacuated objects in the time period and the expected position after the time period; When the evacuation object confirms the advance, updating the position of the evacuation object and the speedthereof; When not advancing, only updating the speed of the evacuated object is ed; finishing the process when the evacuation object completes the evacuation in the current building; Otherwise, executing the process in a loop.

Description

technical field [0001] The invention relates to computer simulation technology, in particular to a method for evacuating crowds in buildings based on a game model of social force evolution of evacuation objects when computer automatically simulates disasters. Background technique [0002] Preventing fires and other disasters and reducing casualties in fire situations have become the focus of research in the field of public safety around the world. With the development of society, people have more and more demand for large buildings, and in these buildings, there are usually a large number of people flowing. The characteristics of these buildings are: firstly, the number of floors is large, the vertical distance is long, and it takes a long time to evacuate to the ground or other safe places; , increasing the difficulty of evacuation. The fire departments of some economically developed cities in my country have purchased a small number of climbing fire trucks, but most citi...
