Problems solved by technology
Although most of the accidents tend to happen in general open road sections rather than in tunnels, due to the closed and underground characteristics of highway tunnels, the accident loss and accident severity are much higher than those in ordinary road sections.
In addition, due to the closed space characteristics of highway tunnels, emergency evacuation in tunnels is more difficult than that of ordinary open highways.
When an accident occurs in a tunnel, it mainly relies on accident lighting and evacuation signs to ensure safe evacuation. However, due to the low visibility and many obstacles in the tunnel, the panicked escapees are rampant because they cannot distinguish the direction, which seriously affects the evacuation of personnel. speed
[0003] Existing research on emergency evacuation of tunnels focuses on simulating the disaster scene, establishing models to analyze the movement rules of vehicles and personnel, and focusing on building an emergency system framework and preparing emergency plans at the technical operation level. However, in emergency evacuation of tunnel accidents, During the process, few people considered the impact of human factor reliability on safe evacuation

Embodiment Construction
[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0037] refer to figure 1 , is a schematic flow chart of a HRA-based tunnel evacuation procedure risk quantification method of the present invention, the method comprising the following steps:
[0038] Step 1: Propose a set of 14 actions to evacuate people in the tunnel under emergency conditions through AHP, as shown in Table 1.
[0039] The escape process begins with the detection of the accident, and if possible, the personnel are directly evacuated out of ...

The invention belongs to the technical field of road traffic safety, and discloses a human reliability analysis (HRA)-based risk quantification method of a tunnel evacuation procedure. Starting from humans, the emergency evacuation procedure of personnel in a tunnel is provided; risk possibility quantification is carried out on each action in an emergency evacuation process of the personnel to obtain human failure probability; a consequence table is adopted to quantificationally analyze severity degrees of consequences which may be caused by failing of each action; finally, the human failure probability and consequence severity are combined to carry out risk quantification on each evacuation action; and ultimately, quantification values are taken as bases, a relevant measure is adopted ina targeted manner according to sizes of the risk quantification values to prefect and improve tunnel operation and management, escape risks are reduced, and tunnel operation safety is improved.
Description
technical field [0001] The invention belongs to the technical field of road traffic safety, and in particular relates to a risk quantification method of a tunnel evacuation program based on Human Reliability (HRA). Background technique [0002] Expressway tunnels are special road sections on expressways. Due to factors such as the increase in traffic flow, the increase in the transport volume of dangerous goods, and the acceleration of vehicle speeds, the tunnel has become a potential accident-prone section. There are chemical leakages, traffic accidents, etc. Or the danger of emergencies such as fire. Although most of the accidents tend to happen in general open road sections rather than in tunnels, due to the closed and underground characteristics of highway tunnels, the accident loss and accident severity are much higher than those in ordinary road sections. In addition, due to the closed space characteristics of highway tunnels, emergency evacuation in tunnels is more d...
