摘要
针对超高层施工平台在超高层建筑施工中的重要性和特殊性,以施工平台事故为顶事件,采用故障树分析法对超高层施工平台风险因素进行辨识和分析,表示出各事件之间的逻辑关系。结合模糊理论,引入模糊概率对基本事件的发生概率进行评价。计算出各基本事件和中间事件的模糊概率重要度,定量分析超高层建筑施工平台事故成因,寻找现场管理的重点。通过项目调研和专家访谈获取基本事件的模糊概率,分析发现施工平台的堆载问题和施工平台安、拆、顶升阶段的人员操作问题对于施工平台的安全事故影响较大,可为超高层建筑施工平台安全管理提供重要参考。
Considering the importance and uniqueness of construction platforms in the construction of super high-rise buildings, we identify the accident of construction platforms as the top event and then identify and analyze the risk factors of construction platforms of super high-rise buildings through fault tree analysis method, showings the causal relationship between events. Then, combined with fuzzy theory, fuzzy probability is introduced to evaluate the occurrence probability of basic events. Fuzzy probability importance of basic events and intermediate events are calculated to quantitatively analyze accident causes of the construction platform of super high-rise buildings and identify the focus of construction site management. Project investigation and expert interviews are used to obtain the fuzzy probability of basic events. The results show that loads on construction platforms and personnel operations during installation, dismantling and lifting construction platforms have a great impact on the accident occurrence of construction platforms. It will benefit the improvement of safety management of construction platforms in super high-rise buildings.
