【摘要】 为了促进甘肃省与兰州市区域经济的发展,提升城市的形象和影响力,甘肃省决定2008年在兰州市城关区盐场堡中心滩建设会展中心。该会展中心东西长234米,南北宽84米,建筑高度29.5米。根据《高层民用建筑设计防火规范》第4.3.1条的规定,建筑高度超过24米,长度超过150米的建筑,应设置穿越该建筑的消防车道,按《高层民用建筑设计防火规范》第6.1.7条的规定,该场馆最远点安全疏散距离不应超过30米。但该展馆在设计中为了满足大空间使用功能的要求,未按规范设置穿过建筑物的消防车道,建筑物中间也不能增设安全出口以满足疏散距离的要求。本文使用FDS数值模拟方法对拟建的甘肃省会展中心建筑工程进行火灾风险安全分析,在现有的建筑设计方案上使用数值模拟方法模拟火灾的发生及发展,通过对输出结果的分析,判断该建筑的设计能否满足消防安全要求,保证人员的安全。论文首先说明了论文研究的背景与意义,第二章介绍了几种建筑火灾烟气数值模拟方法的比较,第三章主要介绍了FDS相关技术基础及使用方法,第四章建立了甘肃会展中心FDS模型,并提出了模型的构建分析,第五章对模型输出结果进行了分析,得出结论。最后对使用数值模拟方法对建筑进行火灾风险评价的应用前景和今后工作的方向作出了展望。更多还原

【Abstract】 In order to promote the development of Lanzhou city Gansu province area economic, improve the image and influence of city, Gansu province decides to establish Gansu exhibit center in Chengguan district in 2008. Gansu exhibit center east and west long 234 meter, south and north long 84 meter, build high 29. 5 meter. Bases prescribe of code for fire protection design of tall buildings 4. 3.1 bar, build high exceed 24 meter, extent exceed 150 meter, intercalate thorough architecture fire control driveway, press prescribe of code for fire protection design of tall buildings 6.1.7 bar, exhibit center apoapsis safety evacuate distance not answer 30 meter. Butthis exhibit center by way of satisfy big interspace use functional request, not press criterion to intercalate thorough architecture fire control driveway, build bosom cat not add anchor-hold exit satisfy evacuate distance of request too. Text use FDS numerical simulation means to Gansu exhibit center build engineering through fire hazard safety analyze, in existing of build design use numerical simulation means simulate fire happen and develop, get across to export result analyze, estimate architectural design if satisfy fire control anchor-hold request, assurer safely of personnel.Discourse first explain discourse inquisitive backdrop and meaning, secondly compare a few grow architecture fire smoke gas numerical simulation means, third mostly introduce FDS numerical simulation means correlation art base and use means, four built Gansu exhibit center FDS numerical simulation model, fifthly analyze to model export result , educe conclusion. Finally numerical simulation means apply foreground and future directions in architecture fire hazard safety analyze.更多还原
