Abstract

Focusing on the core role of municipal bridges in urban transportation, this paper systematically analyzes the importance of safety and durability for traffic safety, public interest, and the stability of urban transportation systems. It proposes pathways for enhancing safety from three aspects: optimizing structural stress, improving protective facilities, and strengthening emergency evacuation. It also constructs a system for reinforcing durability from three aspects: selecting optimal corrosion-resistant materials, designing for drainage and impermeability, and reserving maintenance space. The research results aim to demonstrate that targeted design strategies can effectively reduce bridge safety risks and extend service life, providing a practical and professional reference framework for municipal bridge design, thereby helping to enhance the bridge's whole-life-cycle service capability.
