Problems solved by technology
Because the above-ground space may have functions such as large-scale transportation and comprehensive development, the evacuation stairwells leading to the outdoors in the underground commercial area are often difficult to meet the minimum width requirements for evacuation, or barely meet the code requirements
And limited by the ground design conditions, the scope of setting up a sunken plaza to solve the problem of evacuation is very limited

Embodiment Construction
[0028] Below in conjunction with specific embodiment and attached Figure 1-2 The present invention will be further described.
[0029] Such as Figure 1-2 As shown, a certain project has one floor underground and one floor above ground. On the east and west sides of the basement floor, social car parking garages are mainly arranged, with an elevation of -7.200m. The central part is the subway station hall 9 and commercial facilities 3, with a ground elevation of -9.200m. Among them, the public area of the central subway station hall 9 is about 13380m 2 , each centralized commercial area includes a construction area of about 13110m2 for equipment management 2 , the construction area of each garage area is about 28730m2 2 .
[0030] The above-mentioned design method for improving the fire safety performance of underground commercial facilities supporting traffic buildings includes a sunken plaza 1, an escape corridor 2, and underground commercial facilities 3. The e...

Abstract
The invention relates to a design method for improving fireproof safety performance of underground commercial facilities matched with traffic buildings, and belongs to the technical field of disasterprevention and reduction and protection of building structures. The underground commercial facilities comprise a sunken square, a refuge walkway and underground commercial facilities, wherein the refuge walkway is arranged in the sunken square, and the two ends of the refuge walkway are connected with the sunken square. An underground centralized commercial area is divided into different commercial areas by adopting the refuge walkway in the sunken square; the commercial areas and the refuge walkway are separated by adopting a firewall and a smoke-proof front room. The commercial facilities ineach commercial area are divided into fireproof subareas according to use functions. At least two safety exits are arranged in each fireproof subarea, and can lead to the sunken square or different refuge walkways, or can be directly evacuated to an outdoor area through an evacuation staircase. An evacuation passage with two ends capable of leading to the outside, the sunken square or the refugewalkway is formed in the middle of the underground centralized commercial area.
Description
technical field [0001] The invention relates to a design method for improving the fire safety performance of underground commercial facilities supporting traffic buildings, and belongs to the technical field of disaster prevention, reduction and protection of building structures. Background technique [0002] As the pace of urban construction continues to accelerate, the development and utilization of underground space is gradually increasing. The scale of the underground commercial area is getting bigger and bigger, and the total construction area even reaches tens of thousands of square meters. The smoke exhaust and fire fighting and rescue conditions in the underground space are relatively poor, and the fire load of commercial facilities is relatively high. Once a disaster such as fire occurs, it is easy to cause heavy casualties and property losses. [0003] The density of people in commercial facilities is high, and a large number of people need to be evacuated in case...
