【摘要】：布達(dá)拉宮自興建以來曾遭受多次不同程度雷擊,一旦雷擊引發(fā)火災(zāi)會(huì)造成不可挽回的損失,因此需要進(jìn)行科學(xué)合理的雷擊火災(zāi)分析以有效指導(dǎo)布達(dá)拉宮減災(zāi)工作。對(duì)于布達(dá)拉宮雷電可能引起火災(zāi)的風(fēng)險(xiǎn),建立布達(dá)拉宮雷擊火災(zāi)事故樹,綜合考慮布達(dá)拉宮因雷電引發(fā)火災(zāi)事件發(fā)生的可能過程、可能途徑。最后對(duì)雷擊火災(zāi)事故樹最小割集、最小徑集、基本事件的結(jié)果重要度進(jìn)行比較,同時(shí)分析布達(dá)拉宮地區(qū)雷電活動(dòng)規(guī)律。分析結(jié)果表明:布達(dá)拉宮雷擊火災(zāi)事故樹一共有22個(gè)基本事件,有308種可能導(dǎo)致布達(dá)拉宮因雷擊引起火災(zāi)事件發(fā)生的途徑。布達(dá)拉宮雷擊火災(zāi)防護(hù)是一項(xiàng)復(fù)雜工程。研究表明,最便于采取的防護(hù)措施是加強(qiáng)其雷電防御能力,如清除引雷隱患、安裝電涌保護(hù)器、進(jìn)行等電位連接等。
[Abstract]:Potala Palace has suffered a number of different degrees of lightning strikes since its construction. Once the lightning strikes the fire, it will cause irreparable loss. Therefore, a scientific and reasonable lightning fire analysis is needed to effectively guide the Potala Palace disaster reduction work. For Potala Palace lightning may cause the risk of fire, the establishment of a fire accident tree of the lightning strike of the Potala Palace, Considering the possible process of the fire incidents caused by lightning in Potala Palace, the possible ways are taken. Finally, the minimum cut set, the minimum path set, the important degree of the basic events are compared, and the lightning activity rules of the Potala Palace area are analyzed. The results show that the Potala Palace lightning fire accident tree has 22 There are 308 kinds of basic events that may lead to the fire accident in Potala Palace. Potala Palace lightning protection is a complex project. The research shows that the most convenient protection measures are to strengthen its lightning defense capability, such as removing the hidden danger of lightning, installing surge protector, and conducting equipotential connection.
