【摘要】：本文在对高层建筑施工安全风险评价的研究中运用未确知测度(UM)理论,经过综合分析高层建筑施工中安全事故的特点,最终选取了5项一级指标和19项二级指标,构建了高层建筑施工安全风险评价的指标体系;用信息熵求各指标权重,依照置信度识别准则判断风险等级;并应用于工程实例,成功判定出该工程的综合安全风险等级为Ⅲ级。结果表明,此方法不但能求出高层建筑施工安全风险等级,还可以客观反映施工中危险源的情况,为高层建筑施工安全风险性评价提供有效参考。
[Abstract]:In this paper, the unascertained measure (UM) theory is used in the study of safety risk assessment of high-rise building construction. After comprehensive analysis of the characteristics of safety accidents in high-rise building construction, 5 first-grade indexes and 19 second-class indexes are selected. The index system of safety risk evaluation of high-rise building construction is constructed. The weight of each index is calculated by information entropy, and the risk grade is judged according to the confidence recognition criterion, and applied to the engineering example, the comprehensive safety risk grade of the project is determined to be grade 鈪，
