Abstract


Super high-rise building is part of the iconic buildings in the city,which fully displays theadvanced degree of economy and society. By the statistics,China has been one of the countrieswho has the most high-rise buildings in the world.With the rapid development of superhigh-rise building,the problems such as fire prevention,personnel evacuation, emergencyrelief and building structure design come along.Fire water supply system is the key link of firesystem in super high-rise building,which directly determines the effect of pre-disasterprevention, so the study of the reliability of fire water supply system in super high-risebuilding is indispensible.Through assessing fire water-supply system of super high-rise building,this thesisanalyzes its present situation of reliability consideration from home and abroad and introducesthe characteristic of parallel partition water supply, temporary high pressure series partitionwater supply and constant high voltage series partition water supply.It establishes thereliability model of fire water-supply system by reliability theory and puts into analysis andapplication,the main content as follows:1. By comparing the characteristics of the fire water ways and combined with the actualconstruction management,the thesis concludes that parallel partition water supply is morepractical for the buildings below150m, temporary high pressure series partition water supplyis more fit for the buildings between150m and250m and constant high voltage seriespartition water supply is the most reliable for the buildings more than250m,even300m.2. According to the components and its working principle of high-rise building fire watersupply ways,it establishes three kinds of water supply system reliability models.The thesisanalyzes the influence on system reliability from components of fire water-supply system andtheir possible points of failure in order to put forward the measure of improving the reliabilityof key components by DE phil method.3.Through applying the reliability model of water-supply system to one certain superhigh-rise building,calculating the system reliability of alternative fire water-supply ways,combining with the economic cost of construction and function on the basis of guaranteeingthe system reliability,the thesis determines the final water supply scheme.
