摘要
桥面铺装是活载体系与桥体承载结构之间的传递部分,其自身也同样属桥梁受力体系的一部分,其自身结构对强度、刚度、防裂及耐磨性能上,都有较高的要求。目前,我国使用中的桥梁很多都出现了网裂、横纵向裂缝,甚至还有较严重的碎裂的病害,这些都对桥梁的使用效果及使用寿命造成严重的不良影响。本文浅析这些病害产生的设计和施工方面的原因,并阐述预防此类病害的具体措施和要求。
Deck paving is the transmit part between load system and bridge bearing structure and it also belongs to bridge load carrying system. Its structure has high demands on the strength, stiffness, crack prevention and wear - resisting property. There are net cracks, horizontal and vertical crack in many using bridge, which affect the usage effect and life of bridge seriously. This paper analyzes the causations of these damages from design and construction aspects and states specific measures and demands of preventing them.
