中文摘要：
针对大跨度悬索桥施工过程，提出一种简化的基于模糊层次分析法的风险评估方法。按悬索桥的施工过程划分层次，普查可能出现的风险源，基于模糊层次分析法结合专家调查评分计算各风险源权重。根据权重筛选风险因素，对权重较大的风险因素提出可行的现场应对方案，以便用于施工方现场处理。该方法将模糊数学方法引人大跨度悬索桥施工阶段的风险评估，对施工中可能面对的风险源进行定量评估的同时又减轻了层次分析的复杂性。
英文摘要：
A simplified method based on Fuzzy Analytic Hierarchy Process （FAHP） for risk assessment of a long-span suspension bridge during construction period is presented. Weighing various factors is calculated based on FAHP according to the dividing hierarchy of construction process, the possible risk factors in the general investigation and combining with the expert investigation. Then, the risk factors are selected based on the weight and practical solutions are put forward to the risk factors with higher weight, which is easy for the construction side to operate. For this method, the fuzzy mathematics method introduced into the risk assessment of the construction period of the long-span suspension bridge can make the quantitative evaluation of the possible risk factors in the construction and reduce the complexity of the analytic hierarchy process.
