摘　　要：为有效评价大跨度桥梁挂篮施工风险,以潭江特大桥为背景,根据其挂篮悬臂施工工艺及施工现场组织管理情况,研究了在挂篮悬臂施工过程中影响桥梁施工质量与人员安全的风险因素。首先,进行风险源识别与分析,寻找影响桥梁施工质量和人员安全的风险因素,建立多层次模糊评价模型及评价体系;其次,利用层次分析法计算各层向量,得出影响桥梁施工质量和人员安全风险因素的排序;最后,结合模糊数学原理确定风险评价等级。研究结果表明:潭江特大桥桥梁施工质量和人员安全风险状态为良,与实际情况比较接近。研究成果为保障潭江特大桥施工质量和人员安全提供了有力的科学依据。In order to assess the risk of large-span bridge hanging basket construction effectively,Tanjiang super large bridge was taken as the background.Based on the hanging basket cantilever construction technology and the construction site organization and management,the risk factors affecting the bridge construction quality and personnel safety during the hanging basket cantilever construction process were studied.First,the risk sources were identified and analyzed,the risk factors affecting the bridge construction quality and personnel safety were looked for,and the multi-level fuzzy evaluation model and evaluation system were constructed.Then,the analytic hierarchy process was used to calculate the vectors of each layer to obtain the order of the risk factors affecting the bridge construction quality and personnel safety.Finally,the fuzzy mathematics principle was used to determine the evaluation level.The results show that the risk status of the bridge construction quality and personnel safety is good,close to the actual situation relatively.This study provides a powerful scientific basis to ensure the construction quality and personnel safety for the Tanjiang super large bridge.
