摘　　要：针对上跨营业线斜拉桥转体施工工艺复杂、风险评估难以量化等问题,结合三角模糊数法、贝叶斯网络理论和模糊综合评判法,建立了转体施工工艺全工序风险源层次分析模型。定量分析斜拉桥转体施工过程,根据风险评估及分析结果,对风险等级较高的工序提出了相应的管控措施,保障了上跨营业线斜拉桥转体施工安全。In response to the complex technology and difficult quantification of risk assessment in the rotation construction of the cable-stayed bridge crossing the business lineꎬthe hierarchical analysis model for the risk sources of the entire process of the rotation construction technology is established by combining the triangular fuzzy number methodꎬBayesian network theoryꎬand fuzzy comprehensive evaluation method.The quantitative analysis is made on the rotation construction process of the cable-stayed bridge.Based on the risk assessment and analysis resultsꎬthe corresponding management and control measures are put forward for the processes with higher risk levels to ensure the safety of the rotation construction of the cable-stayed bridge crossing the business line.
