钢桥面铺装的主要病害与防治措施分析

Analysis on Major Diseases and Prevention Measures of Steel Bridge Deck Pavement

钢桥面铺装受钢桥面板的光滑度、柔度、行车荷载、温度变化、风载、地震等多种因素共同影响,使用条件和受力状态十分复杂。文章结合多个工程实例,基于钢桥面板的物理特点,对钢桥面铺装的主要病害以及常用防治措施进行了详细阐述,为今后的钢桥面铺装施工、维修、加固等提供相关经验借鉴。

Steel bridge deck pavement is jointly affected by the smoothness of steel bridge deck, flexibil- ity, ddving load,temperature changes, wind loads, earthquakes and other factors, and the utilization conditions and stress state are very complexin combination with a number of engineering examples, and based on the physical charactedstics of steel bridge decks, this article described in details the major diseases of steel bddge deck pavement and the common preventive measures,thereby providing the relevant expedence reference for the construction, maintenance and reinforcement of steel bridge deck pavement in future.
