灰色关联故障树分析在高大模板支撑系统中的应用

Application of gray correlation fault tree analysis for high formwork support system

高大模板支撑系统的安全性对工程建设至关重要,也对人民群众的生命和财产安全影响深远。为使高大模板支撑系统安全性得到有效控制,预防高大模板坍塌事故的发生,文章采用灰色关联故障树分析方法,对高大模板支撑系统施工中可能出现的各种坍塌模式进行识别并分析其原因;应用灰色关联理论,查找高大模板支撑系统安全性的薄弱环节,对导致高大模板坍塌事故的各种因素及逻辑关系做了全面阐述,并为预防高大模板坍塌事故提供了重要的理论依据。

The safety of the high formwork supporting system not only plays a vital role in the successful engineering construction, but also makes a great difference to people＇ s lives and property. To effectively control the safety of the high formwork supporting system and prevent the collapse accident, we carried out gray correlation fault tree analysis to recognize all kinds of collapse modes, analyzed the main reasons leading to the collapse, and then pointed out the weak links based on the gray correlation analysis theory. The result shows that the gray correlation analysis can make detailed description to factors and a logical relationship that leading to the collapse and provide a theoretical basis for the prevention of the high formwork collapse accident.
