Based on the identification of safety risks during the design phase of urban elevated road ,the risk assessment index system for urban elevated road design is constructed and the safety risk fuzzy comprehensive evaluation model based on entropy weight is established .Through case analysis ,safety risk comprehensive evaluation for one elevated road in design phase is con-ducted ,some improvements and suggestions are given and the feasibility and applicability of the methods is verified .%从城市高架道路设计阶段安全风险因素识别入手，构建了城市高架道路设计安全风险评估指标体系，建立了基于熵权的安全风险模糊综合评价模型，结合工程实例对某高架道路设计阶段安全风险综合评价，给出风险管理改进措施和建议，验证了方法的可行性和适用性。
