Abstract

Abstract: According to the research status of the application of the energy-storage and reflective materials and the characteristics of accidents in highway tunnels，the importance of the energy-storage and reflective materials used in highway tunnel side wall for improving the visual environment of emergency rescue was analyzed.Aiming at the energy-storage and self-luminous characteristics of energy-storage and reflective materials，the tests of afterglow luminance and afterglow spectrums of the energy-storage and reflective materials with two different composition ratios were carried out.The characteristic parameters of the above two kinds of materials，such as the material ratio coefficient，the brightness and duration of afterglow，and the power distribution of afterglow spectral were analyzed and calculated.The results show that the self-luminous brightness of energy-storage and reflective sidewall-material in 1 hour is much higher than the limit the human can recognize.The energy-storage and reflective sidewall-material with 0.3 luminous powder ratio has the best afterglow performance，and the initial brightness and the afterglow duration are significantly improved by this ratio.Silicate light-storage and reflective materials have a higher S/P value of afterglow spectral than the aluminate light-storage and reflective materials do，while the aluminate light-storage and reflective materials have better performance in afterglow brightness.Reasonable selection of the relative parameters of energy-storage and reflective sidewall-materials is helpful to improve the emergency rescue function of highway tunnel emergency accidents and disasters.

Key words: tunnel engineering, energy-storage and reflective sidewall-material, emergency rescue, afterglow brightness, afterglow spectral power distribution

摘要： 结合蓄能反光材料的应用研究现状以及公路隧道突发事故灾害的特征，分析了蓄能反光材料应用于公路隧道侧壁对于改善应急救援视觉环境的重要性。针对蓄能反光材料的蓄能自发光特性开展了两类不同配比的蓄能反光材料的余辉亮度和余辉光谱试验，并对两类蓄能反光材料的特征参数，如材料配比系数、余晖亮度和持续时间、以及余晖光谱能量分布等进行计算分析。结果表明：蓄能反光侧壁材料1 h内自发光亮度远高于人眼的最低识别亮度；0.3发光粉配比的蓄能反光侧壁材料余辉性能最佳，该配比下的余辉初始亮度与余辉时间都有较大幅度的增长；硅酸盐蓄能反光材料比铝酸盐蓄能反光材料拥有更高的余晖光谱S/P值，但铝酸盐蓄能反光材料的余辉亮度特性优于硅酸盐蓄能反光材料，合理选取侧壁蓄能反光材料的相关参数有助于提高公路隧道突发事故灾害条件下的应急救援功能。
