Methods and Criteria of Safety Evaluation for the Design of Highway Bridges

从交通安全角度分析了桥梁安全性设计所需要关注的内容,概括为桥梁交通安全、道路衔接安全、桥下交通安全3个方面,并分析了具体的评价指标和评估方法。针对桥梁的断面设计、与道路速度协调性设计和桥下交通安全设计给出了具体的建议和措施,以使桥梁设计与周边交通基础设施完好协调。

Main contents for bridge safety design are analyzed from the perspective of transportation safety, and are further concluded as bridge transportation safety, safe connection with approaching road, and transportation safety under bridge. Particular methods and criteria for safety evaluation are highlighted. Finally, some recommendations are given from three aspects, bridge sectional design, speed connection between bridge and road, and safety countermeasures of under bridge transportation, to make the designed bridge fit well with the surronndingtransportation infrastructure around site.
