中文摘要：
为研究走廊里人群弯腰疏散行为,组织45名学生进行6组不同初始密度疏散试验,通过录像分析得出不同密度时弯腰疏散基本图,将结果与行走及爬行疏散比较。试验结果表明：弯腰和行走疏散的速度分别是1.4 m/s和1.7 m/s,而爬行疏散速度为0.73 m/s;在密度小于0.5人/m2时,3种疏散方式的流动速度相当;在密度大于0.5人/m2时,3种移动方式速度有明显差异;得出弯腰疏散的速度频率分布图,速度均值为：女生1.02±0.16 m/s,男生1.09±0.2 m/s;在低速度区,女生占很大比重,男生在高速度区的频率较高。
英文摘要：
Bent-over walking 6 runs of experiments, with up behavior of occupants in corridor is studied experimentally in this paper. to 45 students participating in, were conducted with different initial densities. The fundamental diagram of bent-over walking ly analyzing pedestrian flow at low density was obtained by manualthe video recording. The results were compared with pedestrian flow and crawler flow of others. It shows that the free velocity is 1.4 m/s and 1.7 m/s for the bent-over walking and tively, while about 0.73 m/s for crawling. When the density is smaller than 0.5 l/mz walking, respec- , the velocity for these three types of movement behaviors agrees well. While above 0.5 1/m2, there appear clear differences and it can be said that the bent-over walking behavior may be a good way under The frequency distribution of velocity was also inves smoke or heat situation. flow. The mean value of speed is about 1.02 4- 0.16 m/s and 1.09 ＋ 0.2 m/s for female and male students in these experiments respectively. At low velocity region, the female students account for a larger proportion, whereas the frequency of male students is larger at high velocity regions.
