英文摘要：

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 conducted,some improvements and suggestions are given and the feasibility and applicability of the methods is verified.
