摘　　要：强风来袭易引发人体失衡,现有研究对人员安全及人体失衡鲜有涉及。针对良态强风下的人体静态失衡问题,提出4种人体失衡模式,并推导相应失衡临界风速公式,考虑不同失衡因素的影响。研究表明:摩擦失衡和扭转失衡临界风速与摩擦因数有关,人体实际失衡模式为力矩失衡,30°左右风偏角失衡临界风速最低(13.44 m/s);人体因质量和身高的差异会在不同风等级中发生失衡。故大风气象预警信号为黄色、橙色和红色时,人员不宜出门。研究揭示了强风作用下人体失衡特征,为风灾时人员逃生及政府应急管理提供重要借鉴。Strong winds can easily cause human imbalance,and existing research rarely addresses personnel safety and human imbalance.Aiming to address the problem of static imbalance of human body under normal strong wind conditions,four types of human body imbalance modes are proposed,and the corresponding critical wind speed formula for imbalance are deduced,considering the influence of various imbalance factors.The results show that the critical wind speed of friction imbalance and torsion imbalance is related to the friction coefficient.The actual imbalance mode experienced by the human body is torque imbalance,and the critical wind speed of 30°wind angle imbalance is the lowest at 13.44 m/s.The human body will become unbalanced in different wind levels due to variations in weight and height.Therefore,when the wind weather warning signal is yellow,orange,or red,people should avoid going out.The study reveals the characteristics of human imbalance under the action of strong winds and provides an important reference for personnel evacuation and government emergency management during wind disasters.
