[0003]Currently, the research on disaster prevention and rescue facilities of railway tunnels by relevant researchers at home and abroad mainly focuses on the structural design of emergency rescue stations in tunnels or other rescue facilities in railway tunnels. There are few studies on emergency rescue stations at tunnel entrances, and the current disaster prevention and rescue standards and related regulations for railway tunnels in my country are not perfect enough. The fire prevention and control considerations in the design of emergency rescue stations for railway tunnels are not sufficient. For example, the design specifications The regulations on the emergency rescue station at the tunnel entrance are only limited to the description of the structure type and length

The invention discloses a tunnel portal emergency rescue station disaster prevention ventilation facility design method which comprises the following steps: acquiring a first preset parameter, and establishing a railway tunnel portal emergency rescue station model; establishing a fire source model based on the train parameters; fitting the railway tunnel portal emergency rescue station model and the fire source model to obtain a disaster prevention ventilation model of the railway tunnel portal emergency rescue station, and performing simulation calculation on second preset parameters based on the disaster prevention ventilation model to obtain a relation calculation formula and a change curve between the second preset parameters; and obtaining a disaster prevention ventilation scheme of the railway tunnel portal emergency rescue station based on the relation calculation formula and the change curve. According to the method, the design requirements of disaster prevention and ventilation schemes of emergency rescue stations in tunnels with different tunnel portal distances and tunnel cross sectional areas can be met, and a rapid, simple and convenient design method is provided for current railway tunnel portal emergency rescue station ventilation schemes.
Description
technical field [0001] The invention belongs to the technical field of railway engineering construction, and in particular relates to a method for designing disaster prevention and ventilation facilities of an emergency rescue station at a tunnel entrance. Background technique [0002] With the continuous development of tunnel construction in our country, there are more and more new railway tunnels and tunnel groups, and the length of tunnels is constantly being refreshed. With the construction of long railway tunnels and tunnel groups, safety issues of railway tunnels are constantly emerging. Train disasters in railway tunnels can be mainly divided into two categories: derailment and rollover and train fires in tunnels. Among them, the probability of train fires in tunnels Therefore, disaster prevention and rescue in railway tunnels are mainly aimed at train fires. The tunnel structure is narrow and long. Once a fire breaks out in the tunnel, a large amount of toxic smoke ...
