摘　　要：通过回归分析和方差分析,探讨硅钛防火蓬喷淋系统对建筑外立面竖向火蔓延的抑制作用,分析喷洒量、喷洒时间、喷洒角度和喷洒压力等因素对火蔓延速度和火焰高度的影响。回归分析结果表明,喷洒量和喷洒压力对火蔓延速度和火焰高度的抑制作用最为显著,尤其是喷洒压力,增加喷洒量和喷洒压力能显著降低火源温度并有效减缓火蔓延。喷洒角度对火蔓延速度和火焰高度的影响较弱,但仍有一定作用。方差分析进一步验证了各因素的显著性,喷洒量、喷洒压力和喷洒时间对火焰高度和火蔓延速度的影响在统计上均具有显著性。Through regression analysis and variance analysis,the study discusses the suppression effect of silicon-titanium fire-retardant sprinkler system on vertical fire spread of building facade;and analyzes the effects of spraying amount,time,angle and spraying pressure on fire spread speed and flame height.The results of regression analysis show that spraying amount and spraying pressure have the most significant inhibitory effects on fire spread speed and flame height,especially spraying pressure.Increasing spraying amount and spraying pressure can significantly reduce fire source temperature and effectively slow down fire spread.The effect of spraying angle on fire spread speed and flame height is weak,but it still has certain effect.ANOVA further verifies the significance of each factor.The effects of spraying amount,pressure and time on flame height and fire spread speed are statistically significant.
