    摘要:

    以九峰山人行悬索桥为观测点,采用视频记录与人工筛选相结合的方法获取了 2 236个行人样本的实测数据,进而统计得到人行悬索桥上的行人步行参数(步频、步幅和步速)的分布特性和统计值,并给出了人行悬索桥上的步频-步速、步幅-步速和步频-步幅之间的转换关系式,得到以下结论:1)在人行悬索桥上,全部行人的步行参数都服从正态分布,即步频~N(1.726, 0.258)Hz、步幅~N(0.596, 0.094)m、步速~N(1.013, 0.260)m/s,它们的合理性也在某工程实例的应用中得以验证;2)人行悬索桥上的行人步行参数的均值(标准差)要小于(大于)其他行走环境所统计得到的行人步行参数的均值(标准差);3)中国人的步频和步幅的均值(标准差)都小于(大于)西方人的步频和步幅的均值(标准差).因此,在设计我国的人行悬索桥时,不能直接采用其他人种和行走环境的行人步行参数的统计值,而应采用适合于人行悬索桥的步行参数.

    Abstract:

    Taking the Jiufengshan suspension footbridge as the observation site, the measured data of 2 236 pedestrian samples were obtained by video recording and manual screening, and then the distribution characteristics and statistical values of pedestrian walking parameters (step frequency, step length, and walking speed) on the suspension footbridge were statistically obtained. Moreover, the relations among step frequency, step length, and walking speed were also proposed. The conclusions are as follows. 1) On the suspension footbridge, the walking parameters of all pedestrians obey the normal distribution, i.e. step frequency~N(1.726, 0.258)Hz, step length~N(0.596, 0.094)m, and walking speed~N(1.013, 0.260)m/s, and their rationality is also verified in some engineering applications; 2) the mean values (standard deviations) of walking parameters on the suspension footbridge are less (greater) than the mean values (standard deviations) of walking parameters obtained from other walking environments; 3) the mean values (standard deviations) of Chinese step frequency and length are less (greater) than that of Westerners. Therefore, in the design of suspension footbridges in China, the statistical values of walking parameters of other races and walking environments cannot be directly used, while the walking parameters suitable for suspension footbridges should be used.
