随着国民经济的迅速发展,公路客货运输需求激增。公路、桥梁能否提供安全、快速、重载行驶等新要求、新矛盾越来越突出。评估现有桥梁,维修保养现有桥梁,使桥梁能够正常工作,并尽可能延长其使用寿命,这是我国交通科技领域内的一项重大课题。文章从桥梁健康评判角度,分析了对桥梁结构造成损伤的影响机理,构建桥梁健康评判体系,以鹤壁幸福水库桥为例进行实证分析。
With the rapid development of the national economy, the demand for highway passenger and freight transportation surges. Whether roads, bridges and bridges can provide new requirements such as safety, speediness and heavy-haul driving are more and more obvious. Evaluating the existing bridges, repairing the existing bridges, enabling the bridges to work properly and extending their service life as much as possible are a major issue in China’s transportation science and technology field. From the point of view of bridge health assessment, the article analyzes the mechanism of damage to the bridge structure, builds a bridge health assessment system, and takes Hebi happiness Reservoir Bridge as an example for empirical analysis.
