EVALUATION METHOD FOR OCCURRENCE AND STRUCTURAL SAFETY OF TUNNEL USING SENSING EXPLOSIONS AND FIRES

摘要

The present invention includes an allowable value input step of receiving a pressure allowable value, a noise allowable value, and a temperature allowable value for a case in which no accident has occurred in the tunnel; A pressure measurement value, a noise measurement value, a temperature measurement value, and a deformation measurement value are input from the pressure detection unit 10, noise detection unit 20, temperature detection unit 30, and deformation detection unit 40 installed inside the tunnel. Inputting a measurement value; A measurement value analysis step of comparing the pressure allowable value, noise allowable value, and temperature allowable value with the pressure measured value, noise measured value, and temperature measured value to analyze whether explosion or fire occurs inside the tunnel; A deformation evaluation step of evaluating whether the deformation measurement value is due to a long-term deformation or a short-term deformation of the tunnel; In the measurement value analysis step, when it is analyzed that the pressure measurement value exceeds the pressure allowable value, and in the deformation evaluation step, when the deformation measurement value is evaluated to be due to short-term deformation, the deformation measurement value of the tunnel structure By presenting a method for evaluating the stability of a structure by detecting explosions and fires in the tunnel, comprising: a stability evaluation step of evaluating the stability of the tunnel, and detects explosion and fire accidents in the tunnel in real time, and the characteristics and scale of the accident In addition to judging, the safety of the tunnel structure can be quickly determined, so that appropriate countermeasures can be established according to the characteristics of the accident.
