摘要:
为探究隧道火灾复杂环境对人员疏散速度的耦合影响规律，首先对坡度、人体疲劳及能见度3种因素开展疏散试验，获得各单因素对疏散速度的影响规律，并拟合出疏散速度变化公式；其次基于各单因素下速度变化公式，提出多因素耦合影响下隧道火灾人员疏散速度计算方法。研究结果表明：人员上坡疏散速度与坡度线性负相关，下坡疏散速度规律性较弱；长距离疏散时因疲劳导致速度逐渐衰减，在2 km疏散过程中速度衰减峰值达47%，疲劳导致的速度衰减比例与疏散距离线性正相关；能见度较高时其对疏散速度的影响效果不显著，能见度降低至10 m内后开始对疏散速度产生负面作用。研究结果可为隧道疏散设施设计、相关标准规范制定等提供参考，同时为传统疏散速度取值方法提供1个新思路。
Abstract:
In order to explore the coupling influence laws of the complex environment of tunnel fire on the evacuation speed of personnel,the evacuation tests were carried out on three factors of slope,human fatigue and visibility to obtain the influence law of single factor on evacuation speed,and the change formula of evacuation speed was fitted.Based on the speed variation formula of each single factor,a calculation method for the evacuation speed of personnel in tunnel fire under the multi-factor coupling influence was proposed.The results show that there is a linear negative correlation between the uphill evacuation speed and the slope.The regularity of downhill evacuation speed is weak.During long distance evacuation,the speed decreases gradually due to fatigue,and the peak speed attenuation reaches 47% during 2 km evacuation.The proportion of speed attenuation caused by fatigue is positively correlated with the evacuation distance.When the visibility is high,the influence on evacuation speed is not significant.When the visibility is reduced to less than 10 m,it has a negative effect on evacuation speed.The research results can provide a reference for the design of tunnel evacuation facilities and the formulation of relative specifications,and provide a new idea for the traditional evacuation speed valuing method.
