以江顺大桥的斜拉桥方案初步设计阶段安全风险评估为工程背景,采用层次分析(AHP)-模糊聚类(Fuzzy Clustering)-德尔菲(Delphi method)综合风险评估法(AFD法),进行建设条件风险评估、结构方案风险评估、施工技术风险评估和工程运营管理4个准则层风险评估的研究。以工程实际情况及专家经验为基础确定风险源,通过层次分析确定风险准则层权重、子层权重和风险源权重。采用模糊聚类分析的方法对每个风险源的专家打分给出综合总评结果以确保专家打分结果的有效性。对专家打分数据进行分析后,结合层次分析权重结果,获得单项风险源风险水平、准则层风险水平和该项目方案整体风险水平。结果表明,该方案综合风险等级为Ⅱ级,属中度风险。本文提出的AFD法用于工程设计安全风险评估是可行的。
以江順大橋的斜拉橋方案初步設計階段安全風險評估為工程揹景,採用層次分析(AHP)-模糊聚類(Fuzzy Clustering)-德爾菲(Delphi method)綜閤風險評估法(AFD法),進行建設條件風險評估、結構方案風險評估、施工技術風險評估和工程運營管理4箇準則層風險評估的研究。以工程實際情況及專傢經驗為基礎確定風險源,通過層次分析確定風險準則層權重、子層權重和風險源權重。採用模糊聚類分析的方法對每箇風險源的專傢打分給齣綜閤總評結果以確保專傢打分結果的有效性。對專傢打分數據進行分析後,結閤層次分析權重結果,穫得單項風險源風險水平、準則層風險水平和該項目方案整體風險水平。結果錶明,該方案綜閤風險等級為Ⅱ級,屬中度風險。本文提齣的AFD法用于工程設計安全風險評估是可行的。

As part of design stage,the combined AHP-Fuzzy Clustering-Delphi method(AFD method)is put forward to analyze and assess the safety risk of Jiangshun cable-stayed bridge. Risk assessment of Jiangshun ca-ble-stayed bridge scheme is carried out in the following four standard layers construction condition risk,struc-ture scheme risk,technology risk and management risk. Based on the engineering background and experience of experts,the risk factors are defined. In order to ensure the accuracy of experts’assessment,fuzzy clustering method is used to analyze the results from experts. Then,combined with the result of risk weight from AHP,the risk rank of risk factors,risk layers and the whole bridge scheme are worked out. The result shows that the risk rank of cable-stayed bridge is II,which is of medium risk. The paper concludes that the AFD method is feasible.
