摘　　要：以建筑施工安全系统的触电事故为例,以脆弱性理论为基础,将从2013-2020年期间发生的202起触电事故中提取出25个事故致因按照暴露因素和自身应对能力因素和二因素各自的人、机械、环境、管理归类为2类4种脆弱性因素。基于N-K模型计算各脆弱性因素耦合度,发现建筑施工安全系统中的脆弱性因素耦合度越大,触电事故发生的概率越大;当人、机械、环境、管理因素完全耦合时,建筑施工安全系统脆弱性最大。这个结论对提高建筑施工过程中用电安全管理有参考价值。In order to study the vulnerability under the internal and external risk coupling of construction safety system,improve the safety of construction safety system.Taking the electric shock accident of the building construction safety system as an example,based on the vulnerability theory,25 accidents caused from 202 electric shock accidents from 2013—2020 are classified into 2 vulnerability factors according to exposure factors,coping factors,machinery,environment and management of the two factors.Subsequently,the coupling degree of each vulnerability factor is calculated based on N-K model,and it is found that the greater the coupling degree in the construction safety system,the greater the probability of electric shock accident;When human,machinery,environment and management factors are fully coupled,the vulnerability of the construction safety system is the greatest.The study clarifies the key coupling risk of the vulnerability factors in the construction safety system,and provides an effective reference value for improving the electricity safety management in the construction process.
