摘要
如何使塔吊更好地发挥塔吊真正的效用,避免施工安全事故发生,是建筑业面临的亟需解决的难题。首先分析了塔吊方面常发事故类型,结合塔吊进入施工现场后的作业模式,构建了事故树模型,计算事故发生的最小割集和最小径集后,得出导致严重事故的主要底风险因素,其结果可为管理者降低施工现场塔吊安全风险提供决策支持,提高了决策的效率、精准性。
How to make the tower crane better play the real utility of the tower crane?It is a difficult problem to the construction industry how to avoid construction safety accidents needs to be solved urgently.Firstly,the types of frequent accidents were analyzed in tower cranes.Combined with the operation mode of the tower crane after entering the construction site,the accident tree model was constructed.The minimum cut set and minimum diameter set where the accident occurs were calculated.The main underlying risk factors leading to serious accidents can be derived.This result can provide decision-making support for managers to reduce the safety risk of tower cranes on the construction site,and improve the efficiency and accuracy of decision-making.
