Evaluation Of Reliability Of The Fire Protection System In Underground Business Constructions

During the process of large-scale exploitation and using of underground space, people pay foremost attention to safety problems. Potential hazardous factors of underground space is far more to ground because of its particularity. Especially when the fire occur, the losing of fire is far more excessive than ground space due to the difficulty of refuge and extermination. On the basis of summarizing fire actuality and characteristic of internal and overseas, the paper especially analyses the fire particularity of underground business constructions and discusses the dominant action of the reliability of the fire protection system to exterminate and prevent the occurrence of fire. On the basis of establishment of reliability of the fire protection system in underground business constructions' index system and confirming method of each gunderling system(component)'s weights, the paper ascertains comprehensive judgement system and model of reliability of the fire protection system in underground business constructions.The paper imports Analytical Hierarchy Process to calculate and analyse the model of reliability of the fire protection system. By means of establishment of analytical hierarchy model, the paper solves the problem of each subentry's weights of fire protection system preferably using academic method. The paper establishes comprehensive judgement system to the reliability of the fire protection system in underground business constructions, investigates and analyses the calculational evaluation method of the reliability of automatic sprinkling system and fire alarm system primarily and ascertains the reliable grade at the same time. On the basis of these work, the paper attempts to use the theory and method of reliability of the system to evaluate the reliability of the fire protection system of the underground business constructions for the first time. The paper applys the method of safety check list analysis to the reliability of the fire protection system's rule of law judgment so as to compare to the evaluating result of the compositive evaluation system.
