Problems solved by technology

[0003] At present, scholars at home and abroad mainly use the simulation method to study the evacuation of personnel in emergency rescue stations. Due to factors such as different commercial software, different input parameters, and operational complexity, it is difficult to unify the standard in the design process.
The emergency rescue station costs a lot. If it cannot meet the evacuation requirements, once an accident occurs, it will cause irreparable and heavy casualties.
On the other hand, the probability of fires in passenger trains in tunnels is extremely low. If overly complicated disaster prevention facilities are installed, the initial investment and subsequent maintenance costs will be huge, and they will remain idle all year round.

example

[0054] An emergency rescue station in the tunnel is designed in the middle of a tunnel, with a length of 550m. A cross passage is set every 50m between the left and right lines of the rescue station, with a total of 11 cross passages. The width of the platform is 2.3m, and the maximum number of passengers on the train is 118 people in the compartment. The evacuation time of the structural design of the emergency rescue station is now obtained through the method provided by the invention.

[0055] Substituting known conditions into formula (H), that is, the number of people Q in the compartment with the largest number of passengers 1 =118 people; emergency rescue station transverse aisle distance L s =50m; emergency rescue station platform width B 1 =2.3m; V is taken as the speed of getting off the vehicle 1 =0.8 person / s; if the safety correction factor η is set to 1.3, then there is

Abstract

The invention discloses a railway tunnel emergent rescue station personnel evacuating time obtaining method. The method comprises the steps that railway tunnel, train compartment and personnel conditions and rescue station relevant parameters are obtained and calculated through a calculation method shown in the description for verification. The emergent rescue station personnel evacuating time obtaining method is built based on a calculation method and railway tunnel personnel evacuating characteristics, the method is easier and more practical compared with software analogue simulation calculation, the calculation result is reliable, and a gap in a railway tunnel emergent rescue station personnel evacuating time theoretical model in China is filled. By means of the method, the design of structural parameters such as an emergent rescue station platform width and transverse channel distance can be guided, the safety of a built emergent rescue station is tested, it is ensured that passengers and train personnel can be effectively evacuated in a railway tunnel, and the railway tunnel disaster-prevention evacuating rescue engineering design is safe, applicable, economical and reasonable.

Description

technical field [0001] The invention belongs to the technical field of railway engineering construction, in particular to the technical field of railway tunnel safety engineering construction, in particular to the design and construction technology of railway tunnel emergency rescue stations. Background technique [0002] With the rapid development of my country's railway construction, especially the rapid development of high-speed railways, a large number of railway tunnels exceeding 10km have appeared in recent years. Considering the possible catastrophic consequences of tunnel fires, the importance of tunnel disaster prevention, evacuation and rescue projects has gradually been recognized. Relevant research scholars, designers and construction personnel attach great importance to it. The construction of the tunnel emergency rescue station is the core of the tunnel disaster prevention and evacuation rescue project. Whether the passenger train on fire can evacuate safely aft...
