基于人因差错的满布式支架安全评估研究

Study on Safety Assessment of Full-Spread Bracket Construction by Mistake

通过分析满布式支架事故成因,发现人因差错为主要安全影响因素,但缺乏相关研究,为此通过有限元模拟,采用多元回归模型—拉松回归模型、肯特指数法—层次分析法,得出支架各阶段人因差错的影响程度、发生概率、产生后果评估模型及各分级方法,最后利用风险矩阵法评估支架施工全过程的安全等级,并在实际工程中验证了该模型的有效性。

Through the analysis on the causes of full-spread bracket accidents,it is founded that the main factor affecting safety is human error,though lacking of related research.Therefore through the finite element simulation,multiple regression model,larsson regression model and Kent index method-analytic hierarchy process(AHP)are used to get the influence degree,probability of occurrence and consequences assessment model and the classification method in different stages of bracket because of human errors.Finally,the risk matrix method is used to evaluate the safety level of the whole process of bracket construction,and the effectiveness of the model is verified in the actual project.
