| 摘 要： | 带挂梁的T型刚构桥在运营过程中，水泥混凝土桥面普遍出现病害，集中表现在桥面开裂、露骨和桥面连续失效等病害。从病害原因分析出发，采取局部设置FYT防水层、植筋、钢纤维混凝土桥面铺装、更换毛勒伸缩缝等综合整治措施，取得良好效果。

| Abstract: | The rigid frame T-bridges with suspending beam had already occurred failures in the cement concrete bridge decking,such as cracking,aggregate exposed and inefficiency of bridge decking joint structure.On the base of analysis for failures,we adopted such intergral measures as building partly FYT water-proof layer,planting steel bars,steel fiber bridge decking and replacing the expansion and contraction seam etc.and acquired good effect,which will supply reference for the following bridge failures curing and protection. |
