With the continuous deepening of the research on the railway passenger line in China, the design parameters of the experience of driving a mobile car group abroad can only be considered. Due to the nationalization of the scale of China's station scale (large train formation, long-term waiting mode, long running distance), the size of the inspection warehouse in the EMU is huge, and the fire protection design (safe evacuation) is provided for the inspection section of the moving section. ) brought new research topics. At the same time, due to the continuous development of China's steel structure construction industry, light steel structure construction industrial plant has strong development prospects, its construction period is short, the cost is low, it can be used for large span, beautiful appearance, modern sense, etc. More and more industrial buildings are being used, such as the Shanghai EMU, which has been designed and built and under construction, and the Guangzhou Shipai EMU inspection library. However, light steel structures have lower fire resistance grades, and large spaces also place new demands on fire compartments.

Check the library profile for a 10-line train. If the spacing of the inner line of the warehouse is 8m, then the total width of the warehouse will be about 100m, and the construction area will be about 50,000 square meters. When the fire resistance level of the warehouse is not lower than the second level, due to the large area, although various measures are taken to separate the side of the side span and the auxiliary warehouse from the process, the corresponding fire separation means is used to divide into the independent fire compartment. However, although due to technical limitations (the vehicles are to be inspected on each line, forming a barrier to evacuate the personnel in the horizontal direction), the evacuation distance is far away during the fire, and the fire protection area is often beyond the current specifications. The area specified. Therefore, under the premise of "people-oriented", how to take effective measures to ensure the evacuation of personnel while meeting the requirements of the production process on the housing area is the focus of research.

Designing road surveying iron for a long time, China's building fire protection design has always adopted "command" specifications (in a sense, it is an administrative regulation) to audit various types of building fire protection design. With the rapid development of China's railway construction, construction engineering New theory, new technologies, new materials, new processes and new concepts are constantly being used in design, and architectural design is becoming more and more conceptualized. In the past, the full application of the “command” specification has not been able to meet the current architectural design requirements, and often does not conform to the current regulations. Therefore, fire protection design requirements should be based on the fire development characteristics of specific buildings to determine their fire protection requirements, and quantitative calculation based fire risk analysis is the main means to understand the basic characteristics of fire processes, for the fire protection engineering system of buildings Rationality, practicability, numerical analysis and demonstration, through calculation to check, to ensure that personnel can be evacuated to the safe area in a certain period of time, this is the current fashion phrase "fire performance" design, but also the fire department special argument Theoretical basis.
