摘要
通过对三块钢筋锈蚀槽板的荷载试验结果的分析 ,探讨了钢筋锈蚀和混凝土保护层脱落后的槽板承载力及破坏形态。试验表明 :钢筋锈蚀引起混凝土保护层顺筋完全脱落后 ,槽板的极限承载力下降 14 %～ 2 5 % ,破坏形态为锚固失效。
By analysis on testing for three trough-form slabs with corroded steel bar,bearing capacity and destroying status of trough-form slabs were approached.It was shown by experiments that after the concrete cover of steel bar scaling off along the steel bar lengthways as a result of steel bar in corrosion.The bearing capacity limit was decreased by 14%～25%,and the destroying status was failure in anchorage.
