Problems solved by technology
[0005] The technical problem to be solved by the present invention is: since there is no emergency simulation scheme suitable for urban underground utility tunnels at present, it is impossible to simulate the inside of the utility tunnel when an emergency occurs. The evacuation scenario of personnel, thus it is impossible to provide reference for the emergency plan for the evacuation of personnel in the actual emergency of the comprehensive utility corridor. Therefore, the technical problem to be solved by the present invention is how to provide an emergency simulation scheme for the emergency of the urban underground comprehensive utility corridor

Embodiment 1
[0064] This example figure 2 Shown is a schematic diagram of the modeling process.
[0065] A method for emergency simulation of urban underground utility corridor emergencies provided in the above-mentioned embodiments includes the following steps:
[0066] S101, the parameter setting unit is based on the "Urban Underground Comprehensive Pipe Gallery Engineering Technical Standard" (GB50838-2015), combined with the construction situation of the national comprehensive pipe gallery, as well as the composition of the personnel entering the corridor, their gender, age, weight, pace, and emergency The characteristics of calmness, nervousness and panic in the situation are used to determine the simulation parameters.
[0067] Ideally: the minimum clear width of the pedestrian passages in the comprehensive utility gallery of the main line and the comprehensive utility gallery of the branch line shall not be less than 0.9m; The long distance is not more than 200m; in the gas, elec...

The invention belongs to the technical field of emergency simulation, and particularly relates to an emergency simulation method for urban underground comprehensive pipe gallery emergencies. The method comprises a parameter setting stage, a simulation platform determination stage, a simulation model construction stage and a simulation result output stage, and provides a personnel evacuation emergency guidance method flow when an emergency occurs in the comprehensive pipe gallery. According to building geometric parameters, gallery-entering personnel types and basic data in the comprehensive pipe gallery, the emergency simulation model is constructed, the personnel evacuation behavior in the comprehensive pipe gallery is simulated, and the emergency personnel evacuation behavior simulationresult is obtained, wherein the gallery-entering personnel types and basic data include sex, age, weight, walking speed, distance from an exit, calming, nervous and panic psychological characteristicsin emergency, conformity factors and the like, and the command guidance coefficient of the communication system, so that reference is provided for an actual emergency personnel evacuation emergency plan, and the blank of no emergency simulation system and model suitable for the comprehensive pipe gallery is filled up.
Description
technical field [0001] The invention belongs to the technical field of emergency simulation, and in particular relates to an emergency simulation method for an emergency in an urban underground comprehensive utility gallery. Background technique [0002] At present, the comprehensive pipe gallery is undergoing large-scale construction in my country, and there may be safety accidents in the professional engineering pipelines in the comprehensive pipe gallery, such as fire, water pipe burst, natural gas pipeline leakage and other emergencies. Considering the destructiveness and uncertainty caused by the emergency itself, it is extremely labor-intensive, financial and material to simulate by constructing an experimental environment, and there is a certain danger in the evacuation experiment under emergency conditions, so simulation analysis is often used to Study the problem of evacuation in specific scenarios, so as to provide reference for the emergency plan of evacuation in ...
