摘要
通过四座桥梁施工过程中一批13m钢筋混凝土预制空心板构件出现早期裂缝的工程实例,分析了裂缝产生的原因,结合数值计算结果,说明了早期裂缝对桥面板结构性能的影响,并对设计、施工及设计规范提出了建议.
In the light of the main reasons causing early cracks of a batch of 13m pre-cast reinforced concrete hollow slab members of four certain bridges, the possibility of the occurrence of cracks is discussed in detail and the influences of the early cracks on structural behavior of bridge slabs are shown by numerical analysis. Effective and valuable anti-cracking measures and technical proposals are recommended from design, construction and amendment of design specifications.
