Embodiment 1

[0064] The structural parameters of the entrance of the cross passage with oxygen supply space in the emergency rescue station of the high-altitude railway tunnel are closely related to the number of evacuated personnel. If the number of evacuated people is large, the requirements for the structural conditions of the cross channel with oxygen supply space are high. Due to the large number of people evacuated in the railway tunnel, the structural parameters at the entrance of the emergency exit should be reasonably designed to ensure that the time spent in the evacuation is the least. Cause secondary casualty accident, the 3rd, reduce the personal safety of personnel evacuating under hypoxic and low-pressure environment. Therefore, measures to widen the gentle slope at the entrance section are taken to solve this problem. In the following, an 18-car passenger train is used as the main train in a double-hole single-track tunnel. According to the "Code for Design of Railway Tunn...

Abstract

The invention discloses a method for designing an oxygen supply space-containing transverse channel of a high-altitude railway tunnel. The method comprises the following steps: S1, arranging the oxygen supply space-containing transverse channel between two main tunnels to communicate the two main tunnels, wherein the oxygen supply space is arranged at the middle position of the transverse channel, a protective door is arranged at the joint of the transverse channel and the main tunnels, and the oxygen supply space-containing transverse channel comprises a protective door connected with an entrance of the main tunnel, a gentle slope section of the transverse channel and the oxygen supply space of the transverse channel; S2, obtaining tunnel construction parameters, tunnel passing train parameters and train personnel parameters; S3, establishing a space transverse channel personnel evacuation dynamic model and obtaining a model structure calculation formula; and S4, based on the type of the high-altitude tunnel, designing the oxygen supply space-containing transverse channel structure according to the model calculation formula obtained in the step S3. By the adoption of the technical scheme, the personal safety problem caused by the severe high-altitude tunnel environment during personnel evacuation can be solved.

Description

technical field [0001] The invention belongs to the technical field of disaster prevention and rescue, and in particular relates to a design method for a cross passage with an oxygen supply space for an emergency rescue station in a high-altitude tunnel. Background technique [0002] With the rapid economic growth, in order to promote the economic development of Tibet, enhance national unity, improve the regional railway network layout, and improve the living standards of people of all ethnic groups along the line, high-altitude railway tunnels have developed rapidly, and large-scale tunnel groups have grown in western mountainous areas. The number has increased, and the construction of tunnels leading to high-altitude areas such as Tibet has developed rapidly, and more and more high-altitude long tunnels have emerged. Due to the particularity of high-altitude tunnel engineering, in order to ensure the safety of long tunnel operation, more and more attention has been paid to...
