【摘要】：建设工程是我国国家建设的重要组成部分,建筑企业是国民经济的支柱产业。改革开放30年来,我国建筑业发展很快,高层建筑的高度和数量得到了飞速增长,形成了摩天大楼建设的热潮。建筑业的伤亡事故率一直都远远高于其他行业的平均水平,各类事故中高处坠落更是占最大比例。特别是超高层建筑施工阶段,人员和物体坠落事故的发生会造成人员伤亡和极大的负面社会影响。本文是结合故障树-层次分析法(FTA-AHP)和本人多年在超高层建筑施工一线的实际应用,对超高层建筑高处坠落的原因进行了全面的分析。本文以上海市陆家嘴金融贸易区某超高层建设工程施工实例作为研究对象进行分析,对造成高处坠落的个体和共性原因进行逐条逐项的分析和研究。并通过分别建立人员和物体高处坠落的故障树,使用故障树分析法(FTA)辨识超高层建筑施工中高处坠落事故发生的原因,选择其中安全影响较大的要素。利用层次分析法(AHP)评价各项要素,确定各要素的权重,找出关键要素。基于上述对于各项要素的权重分布的研究,本文提出了有针对性的具体防护方案,这些防护措施方案在某大厦工程中得到了应用并取得了明显的效果。
[Abstract]:Construction engineering is an important part of national construction in our country, and construction enterprise is the pillar industry of national economy. In the past 30 years of reform and opening up, the construction industry of our country has developed rapidly, and the height and quantity of high-rise buildings have been increasing rapidly. The accident rate of the construction industry has been far higher than the average level of other industries, and the highest proportion of all kinds of accidents is falling from high to low, especially in the construction stage of super high-rise buildings. People and objects fall accident will cause casualties and great negative social impact. This paper is based on the practical application of FTA-AHP (Fault Tree Analytic hierarchy process) and myself in the construction of super high-rise buildings for many years. In this paper, the reasons for the fall of super high-rise buildings are comprehensively analyzed. This paper takes a case study of a super high-rise building project in Lujiazui Financial and Trade area of Shanghai as the research object. The article analyzes and studies the individual and common causes that cause the fall from high to high, and establishes the fault tree of people and objects falling from high place, The fault tree analysis method (FTAA) is used to identify the causes of high fall accidents in the construction of super high-rise buildings, and to select the factors which have a great influence on safety. The AHP method is used to evaluate the factors, determine the weight of each factor, and find out the key elements. Based on the above research on the weight distribution of various elements, this paper puts forward specific protection schemes, which have been applied in a certain building project and have achieved obvious results.
