研究一种主观评价与客观计算相结合的方法评价大跨径桥梁施工阶段的风险，从而使大跨径桥梁施工阶段的风险得到有效控制。以大跨径桥梁施工过程为研究对象，对影响大跨径桥梁施工阶段的各风险因素进行归类分析，在此基础上建立风险评价体系，并通过层次分析法（AHP）计算指标权重，制定相应的评判标准评价风险等级，再利用灰色聚类评价法分析桥梁工程项目风险指标的白化权函数及灰色聚类系数，确定其综合风险等级。结合西宁市海湖新区通海桥项目进行分析应用，为今后在桥梁施工阶段有效地规避和防范风险，从而为保障施工过程的安全性提供参考。

A method that the subjective evaluation and objective calculation are combined to evaluate the construction phase risk of the large span bridge will effectively control the risk. The object of study is the construction of large span bridge,the risk factors that affect the construction phase of large span bridge are analyzed,on this basis,a risk evaluation system is set up. The weight of each risk indicators is calculated by analytic hierarchy process(AHP),and the corresponding evaluation criteria is established to evaluate the risk level. And this paper analyses whiten function and gray clustering coefficient of bridge project risk indicators using gray clustering evaluation method,and determines the integrative level of risk. The analysis and application of risk combined with the Tonghai bridge project in Qinghai can provide a reference to effectively avoid and prevent risks in bridge construction phase,so as to ensure the safety of the construction phase.
