| 古建筑的消防安全工作作为古建筑保护工作内容的重要组成部分,需要深入开展的消防科学的研究工作。目前在我国,缺少关于古建筑防火安全方面的规范,通常使用的处方式规范一般不适用于古建筑。性能化方法能够提供更加灵活和符合实际的解决方案。并且这可能是唯一可行的使古建筑达到可接受风险水平的方法。以布达拉宫东大殿为研究对象,探讨了性能化防火分析方法在古建筑防火保护中的应用。以对古建筑进行早期探测报警为目标进行了消防设施设置。应用FDS软件进行了模拟研究,根据模拟结果进行分析,得到了一些有益的结论并应用于消防设施设置。通过对探测器响应时间分析,探测器的设置合理,能够在第一时间报警,并且实现了消防安全设计的科学化、合理化和成本效益的最优化 |

| The fire protection about heritage buildings is an important part in the protection of the heritage,which needs deeper research in the science of fire protection about heritage buildings.China is lack of specific national regulations for these buildings.General prescriptive regulations can often not be met the need of heritage buildings fire protection and sometimes detrimental.In effect,a performance-based approach could offer a more robust and practical solution.It may also be the only viable means of achieving an acceptable level of fire safety in heritage buildings.The paper takes East Main Hall of Potala Palace as the research object,and the application of performance-based fire protection method in heritage buildings is discussed.The paper takes detection fires at the early stage as the object to set fire fighting facilities.FDS is used to do the simulation.By analyzing the results of simulation,some beneficial conclusions were gained and then used in the setup of fire protection establishment.Through analyzing the response time of fire detector,the setup of fire detectors are reasonable and they can give an alarm in first time.The method can realize fire protection design scientific,rationalization and cost-benefit optimization. |
