本文简述了河北省京秦高速公路养护现状,展示了高速公路桥梁使用性能衰减趋势,以桥梁承载能力、通行能力及抗洪能力为基础,对桥梁适应性评定提出了一种新的量化思路,并引入桥梁“健康值”的概念,旨在为今后工程师及养护部门对于类似大数量、简单结构的高速公路桥梁养护、加固提供参考与启发。 In this paper, the status quo of the maintenance of Jing-Qin Expressway in Hebei Province is briefly reviewed. The degradation tendency of expressway bridge performance is demonstrated. Based on the carrying capacity, capacity and capacity of the bridge, a new quantitative approach is proposed for the adaptability assessment of bridges. And introduces the concept of bridge “health value ”, which is intended to provide references and inspiration for future engineers and maintenance departments in the maintenance and reinforcement of similar large number and simple structure of expressway bridges.
