基于模糊故障树的悬挑脚手架坍塌事故风险分析

摘要

悬挑脚手架作为高层建筑施工中被广泛运用的作业平台,其结构特点、搭设方式与普通的落地脚手架有所不同.针对悬挑脚手架的特点,文章以某型钢悬挑脚手架工程为例,运用模糊故障树分析方法,分析了悬挑脚手架在搭设、使用与拆除阶段中可能导致架体坍塌的风险因素,并提出相应的防范措施.%Cantilever scaffold is a work platform which is widely used in high-rise building construction, its structural features and erection way are different from common ground scaffold. According to the characteristics of cantilever scaffold, this article utilizes the fuzzy fault tree analysis method, analyzes the risk factors which might cause the collapse of scaffold in the phase of the build-up, use and removal based on a steel cantilever scaffold project, and puts forward the corresponding preventive measures.
