摘要
超高层建筑具有高度高、结构复杂、施工安全管理难度大等特点。针对超高层建筑施工的安全问题,基于可靠度理论提出了超高层建筑施工事故风险评估方法。通过文献调研、专家访谈,构建了超高层施工事故风险荷载与风险抗力指标体系,确立了风险荷载和风险抗力测度指标及量化表达方法,提出了风险抗力对风险荷载发生概率的修正方法,并结合风险事故后果评价建立了施工事故风险定量评估方法。这可有效降低超高层建筑施工风险、提升施工安全管理水平。
Super high-rise buildings are characterized with high height, complex structure, and tough construction safety management. Aiming at the safety issue, a reliability-based method to evaluate accident risks of super high-rise buildings under construction was proposed. Through investigation of literature and interview with experts, a index system of risk loads and risk resistance construction accidents for super high-rise buildings was constructed and the measurement metrics were determined. Then an approach to adjusting the probability of risk loads by risk resistance was presented, and the quantitative risk evaluation method was built as well by combining risk consequence assessment. The proposed method could effectively reduce the risks of super high-rise buildings under construction and thus improve the levels of safety management for super high-rise building under construction.
