摘要:
为探究多种因素对书架群燃烧的影响，对书架间距的设定提出优化方案，依据实地调研结果和相关规范，建立书架间距影响燃烧FDS模型，根据释热率增长阶段将书架群燃烧过程划分为3个时期，提出释热量增量极限值I(HRR)的概念，研究上架率、书架框架数、书架排数和火源位置在不同书架间距时对书架群燃烧的促进程度。研究结果表明：书架排数相较于上架率、火源位置、框架数而言对书架群燃烧的影响更为显著，应作为图书馆防火设计时的主要考虑因素；从防火角度建议0.8 m或0.85 m作为借阅室的书架间距优选值，1.15 m作为阅览室或新建图书馆的书架间距优选值，1.05 m作为书架间距避开值。
Abstract:
In order to explore the influence of various factors on the combustion of bookshelf group, and propose the optimization scheme for the setting of bookshelf spacing, a FDS model on the combustion under the influence of bookshelf spacing was established according to the field survey results and the related norms. The combustion process of bookshelf group was divided into three periods according to the growth stage of heat release rate (HRR), and the concept of the incremental limit value of heat release rate I(HRR) was proposed. The promotion degree of the rate on the shelf, the number of bookshelf frames, the number of bookshelf rows and the position of fire source on the combustion of bookshelf group under different bookshelf spacing were studied. The results showed that the influence of the number of bookshelf rows had more significant influence on the combustion of bookshelf group compared with the rate on the shelf, the position of fire source and the number of bookshelf frames, so it should be taken as the main consideration factor in the fire protection design of library. From the perspective of fire prevention, it was recommended that 0.8 m or 0.85 m should be the preferred value of bookshelf spacing for the borrowing room, 1.15 m should be the preferred value of bookshelf spacing for the reading room or the newlybuilt library, and 1.05 m should be the avoidance value of bookshelf spacing.
