高空坠物落点研究对建筑高空坠物的安全防护设计具有意义,目前的研究主要偏重于统计和经验。基于高空坠物的物理过程,考虑空气阻力的影响,提出了高空坠物落点理论模型;基于高空物体意外踢落过程中的能量转换,提出了高空物体意外踢落后水平初始速度计算的理论公式;根据施工现场坠落物的特点,基于高空坠物落点理论模型,计算了施工现场高空坠物散落半径,给出了施工现场地面安全防护水平宽度。 The research on the fall of a falling object has significance for the design of the safety protection for falling objects in a building. The current research mainly focuses on statistics and experience. Based on the physical process of falling objects and considering the influence of air resistance, a theoretical model of dropping objects was put forward. Based on the energy conversion during the accidental kick-off process of upper-air objects, a theoretical formula for calculating the initial velocity of upper- According to the characteristics of the falling objects on the construction site, the falling radius of the falling objects at the construction site was calculated and the horizontal width of the ground safety protection at the construction site was given based on the theoretical model of falling objects falling.
