Abstract

Abstract To reduce the hazards of collapse accidents in the construction process and to ensure that the lives, health, and property of construction workers are protected, this study used the theory of safety system engineering to identify the hazards of collapse accidents, analyze the hazards, predict the consequences, evaluate the systemic risks, and evaluate the effects and improve them. At the same time, the risk factors of collapse were evaluated qualitatively and quantitatively by using the analysis methods of fault tree analysis (FTA) and the analytic hierarchy process (AHP). Finally, according to the evaluation results, the main factors causing collapse accidents were found; this provided a reliable and practical basis for the prevention of collapse accidents. Then, according to the decisive factors, corresponding measures were taken in advance to achieve the aim of preventing and controlling collapse accidents. The results show that equipment maintenance, material inspection, and construction site safety management play an important role in preventing collapse accidents.

基于“事故树-层次分析法”的坍塌事故安全决策分析

摘要为了降低建筑施工过程中倒塌事故的危害，保障建筑施工人员的生命、健康和财产安全，本研究运用安全系统工程理论，对倒塌事故的危害进行识别、危害分析、后果预测、系统性风险评估，并对影响进行评价和改进。同时，采用故障树分析(FTA)和层次分析法(AHP)对倒塌危险因素进行定性和定量评价。最后，根据评价结果找出了导致坍塌事故的主要因素;这为防止塌方事故的发生提供了可靠和实用的依据。然后，根据影响坍塌事故的决定性因素，提前采取相应措施，达到预防和控制坍塌事故的目的。结果表明，设备维护、材料检验和施工现场安全管理在预防倒塌事故中发挥着重要作用。
