摘　　要：根据兰州地铁下穿黄河隧道的工程概况及工程水文地质环境条件,然后介绍了集德尔菲法、模糊综合评判和网络分析法于一体的模糊网络分析法,识别了该项目施工的风险源并构建了施工风险评价指标体系,最后通过分析得出该项目具有较高的施工风险,工程实际施工中盾构穿越特殊地段,地层稳定性差,安全管理制度不健全和穿越河堤、引桥、路基以及建筑物等施工因素产生的风险比较大,需要设置专门的风险管理机构进行风险的控制和转移.According to the geological, hydrogeological and environmental conditions of the project of Lanzhou Subway Tunnel under the Yellow River, the fuzzy network analysis method which combines Delphi method, fuzzy comprehensive evaluation and network analysis method is presented,the risk of the project construction is analyzed and the risk evaluation index system of the construction is established. Finally, it is concluded that the project has high risk. The project crosses the special location of river banks, approach river, roadbed and buildings in area of poor stability formation and the safety management system is not perfect,so it is necessary to set up a special risk management institution to control these risks.
