通过结合运用故障树法和层次分析法，从技术风险因素、人员风险因素、自然环境因素、材料设备风险因素五个部分分析了桥梁在施工过程中面临的风险。介绍了层次分析法进行风险分析的基本过程，并结合桥梁风险评价研究了论文中各级指标的重要性程度，找出在桥梁施工过程存在的风险事件，为桥梁的风险分析提供参考。%The paper analyzes the bridges construction risks by using the Fault Tree Analysis and Analytic Hierarchy Process from personnel factors, technical factors, external environment factor, material and equipment risk factors. It describes the process of risk analysis by using Analytic Hierarchy Process, combined with the bridge risk evaluation, researches the importance of all levels of index in the papers, and tries to find out the risk event in bridge construction, providing reference for the risk analysis for the bridge construction.
