结合预应力混凝土连续梁桥工程实例,研究悬臂施工连续梁桥施工过程风险因素识别。阐述了风险识别的基本原理与模糊层次分析基本概念。根据预应力混凝土连续梁桥悬臂施工的特点,以模糊判断分析为主,有限元分析为辅,并结合施工现场的施工控制情况,对连续梁桥在悬臂施工过程可能发生的风险因素进行分析,排出各种风险因素优先级顺序。通过分析表明:模糊层次分析方法较适合于工程建设风险识别,并可为后续的风险分析与工程决策提供参考。
Combined with the engineering example of prestressed concrete continuous girder bridge, the risk factors of cantilever construction continuous girder bridge construction process are studied. The basic principles of risk identification and the basic concepts of fuzzy AHP are described. According to the characteristics of cantilever construction of prestressed concrete continuous girder bridge, fuzzy judgment analysis is the main method and finite element analysis is used as auxiliary. Combined with the construction control of construction site, the risk factors of continuous girder bridge in cantilever construction process are analyzed. Discharge various risk factors in order of priority. The analysis shows that the fuzzy AHP is more suitable for engineering construction risk identification and can provide reference for the subsequent risk analysis and engineering decision.
