将建筑施工中临边坠落的特性模型化,对于预防建筑施工中伤亡事故具有重要的意义。在分析人或物临边高处坠落事故特点的基础上,给出施工工作面内外2种危险源影响空间范围的定义及其数学表达函数,构建相应的危险源影响空间中危害能量分布的数学模型,提出它对人体不同部位伤害程度的评估分析思路,并在大面积碰撞和小面积碰撞2种情况下,建立该危害能量对人体头枕部伤害程度的评估分析方法。通过上海某个6层框架结构教学楼案例,对上述数学模型和评估分析方法进行验证。这为在进行施工计划安排时,考虑危险源影响空间的影响,降低安全事故发生的可能性创造条件,也为安全事故事前预防提供新思路。
It is significant to prevent casualty accidents in building construction by modeling the characteristics of temporary border fall in building construction. Based on the analysis of the characteristics of falling accident at the height of people or objects, the definition of spatial extent of two kinds of dangerous sources inside and outside the working face and its math expression function are given, and the corresponding dangerous sources are given to establish the mathematics of hazardous energy distribution in space Model, and puts forward the idea of how to assess the injury degree of different parts of human body. In the two cases of large-area collision and small-area collision, this paper establishes the evaluation and analysis method of the harm energy to human head and occipital injury. Through a case of a 6-storey teaching building in Shanghai, the above mathematical models and evaluation methods were verified. This creates conditions for considering the impact of dangerous sources on the space, reducing the possibility of accidents and providing new ideas for precautionary measures in the event of construction plans.
