| 摘 要： | 通过一座公路桥梁施工过程中一批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,结合荷载试验的实测结果,说明了早期裂缝对桥面板结构性能的影响,为今后判断具有同类裂缝缺陷的预制薄壁构件能否满足两种极限状态的设计要求提供了有参考价值的技术依据。

| Abstract: | According to the fact that early cracks
in construction appeared in a batch of pre-cast reinforced concrete hollow slab
members,the causes of the craks are discussed in detail.By loading test data,the
influences of the early cracking on structural behavior of bridge slabs are shown.In order
to judge if these crack members can meet the design requirements under two extreme
states,some valuable suggestions are given. |
