【摘要】：超高層建筑屬于城市中標(biāo)志性的建筑物，其充分展示出經(jīng)濟(jì)與社會的先進(jìn)程度，據(jù)統(tǒng)計，目前我國已是世界上超高層建筑數(shù)量最多的國家。超高層建筑迅速發(fā)展的同時，也帶來了諸如火災(zāi)等災(zāi)害防控、人員疏散與應(yīng)急救援、建筑結(jié)構(gòu)及安全設(shè)計等難題。超高層建筑消防給水系統(tǒng)是超高層建筑消防系統(tǒng)設(shè)計最關(guān)鍵的一環(huán)，直接決定了超高層建筑災(zāi)前預(yù)防的效果。而目前國家沒有針對超高層的防火設(shè)計規(guī)范，因此對超高層建筑消防給水系統(tǒng)可靠性的研究十分必要。 本文以超高層建筑消防給水系統(tǒng)為研究對象，分析了國內(nèi)外針對超高層建筑消防給水可靠性研究的基本現(xiàn)狀，對目前超高層常用的三種給水方式，即并聯(lián)分區(qū)給水方式、臨時高壓串聯(lián)分區(qū)給水方式、常高壓串聯(lián)分區(qū)給水方式的特點(diǎn)進(jìn)行分析介紹，運(yùn)用可靠性理論建立消防給水系統(tǒng)可靠性模型，并進(jìn)行分析應(yīng)用。主要內(nèi)容如下： 1、通過對比各消防給水方式特點(diǎn)并結(jié)合實際施工管理，得出了在150m以下的超高層建筑，使用并聯(lián)分區(qū)給水方式較為實用，而150m-250m之間的超高層，應(yīng)采用臨時高壓串聯(lián)分區(qū)給水方式，超過250m特別是超過300m的建筑，采用常高壓串聯(lián)分區(qū)給水方式的給水方式才最為安全可靠的結(jié)論。 2、根據(jù)超高層建筑消防給水系統(tǒng)組成的元件及其工作原理建立三種給水方式下系統(tǒng)的可靠性模型，根據(jù)某地超高層建筑的調(diào)查數(shù)據(jù)利用德菲爾法確定給水系統(tǒng)各元件的可靠性，對比分析消防給水系統(tǒng)各元件對系統(tǒng)可靠性的影響程度，分析元件可能存在的故障點(diǎn)并提出提高關(guān)鍵元件可靠性的措施。 3、將給水系統(tǒng)的可靠性模型應(yīng)用到某一超高層建筑中，計算備選消防給水方式的系統(tǒng)可靠性，，在保證系統(tǒng)可靠性的基礎(chǔ)上結(jié)合建筑的經(jīng)濟(jì)成本及使用功能，確定最終的給水方案。
[Abstract]:Super high-rise buildings belong to the iconic buildings in the city, which fully show the advanced degree of economy and society. According to statistics, China is now the country with the largest number of super high-rise buildings in the world. Along with the rapid development of super high-rise buildings, such as fire disaster prevention and control, personnel evacuation and emergency rescue, building structure and safety design and other difficulties. The fire water supply system of super high-rise building is the most important link in the design of fire protection system of super high-rise building, which directly determines the effect of prevention before disaster of super high-rise building. At present, there is no fire protection design code for super high-rise building, so it is necessary to study the reliability of fire water supply system for super high-rise building. Taking the fire water supply system of super high-rise building as the research object, this paper analyzes the basic status of the research on the reliability of fire water supply for super high-rise building at home and abroad, and analyzes the three kinds of water supply modes commonly used at present, that is, parallel partition water supply mode, which are commonly used in super high-rise building at present. The characteristics of the temporary high pressure series water supply system and the normal high pressure series water supply system are analyzed and introduced. The reliability model of the fire water supply system is established by using the reliability theory, and the reliability model is analyzed and applied. The main contents are as follows: 1. By comparing the characteristics of each fire water supply mode and combining with the actual construction management, it is concluded that in the super high-rise buildings below 150m, it is more practical to use the parallel partition water supply mode, and the super high-rise building between 150m-250m, The safe and reliable conclusion is that the temporary high pressure series water supply system should be used, especially for buildings with more than 250 m, especially more than 300 m, and the normal high pressure series zone water supply mode should be adopted. 2. According to the components and working principle of fire water supply system in super high-rise building, the reliability model of the system under three kinds of water supply modes is established. According to the investigation data of super high-rise buildings in a certain place, the reliability of each component of water supply system is determined by using the Defel method, and the influence degree of each component of fire water supply system on the reliability of the system is compared and analyzed. The possible fault points of the components are analyzed and the measures to improve the reliability of the key components are put forward. 3. The reliability model of water supply system is applied to a super high-rise building, the system reliability of alternative fire water supply mode is calculated, and the economic cost and use function of building are combined on the basis of ensuring system reliability. Determine the final water supply plan.
