【摘要】 传统的消防预案无法充分和直观地表现建筑物空间结构,火灾模拟可以在一定程度上满足对火灾预测的需求。在火灾数值模拟方法中,区域模拟方法有其独有的优势,它对计算机硬件要求较低,计算结果与实验结果符合的较好。以CFAST为代表的区域模拟软件得到了广泛应用,但是CFAST的操作复杂,模拟结果无法显示烟气浓度。对CFAST接口标准进行分析,将三维建筑物建模软件作为CFAST的建模工具,并将CFAST数值模拟结果显示在该软件的建筑物模型中。可以动态显示出不同时刻烟气浓度,弥补了CFAST在可视化方面的不足,为消防人员制定火灾救援预案提供参考。更多还原

【Abstract】 Traditional fire rescue scheme can’t display the structure of building adequately and intuitively.Fire simulation can be satisfied with the need of fire forecast to some extent.Among the method of fire numerical simulation,zone modeling has some advantages,for example,it needs less support of computer hardware and its computing result consists with the experiment result well.Zone modeling software,which takes CFAST as representative,is used widely.But its operation is complex and its simulation result can’t display gas thickness.According to analyzing the interface standard of CFAST,a software of three-dimentional building modeling is used as CFAST’s modeling tool,in which the result of CFAST numerical simulation displays.Through the combination of the software and CFAST,it can show different moment of gas thickness,remedy the deficiency of CFAST on visualization,provide reference for firefighters to establish fire rescue scheme.更多还原
