预应力碳纤维板在T梁桥加固中的应用与试验

Application and Test for T Girder Bridge Strengthened by Prestressed Carbon Fiber Board

采用外部粘贴预应力碳纤维板对承载能力不满足要求的装配式混凝土T梁桥进行加固,并对比加固前和加固后该桥的荷载试验检测结果,表明预应力碳纤维板加固能有效利用碳纤维板的结构强度,显著提高桥梁的承载能力。

The prefabricated concrete T girder bridge which cannot meet the requirements of the load bearing capacity was reinforced by external bonded Prestressed carbon fiber board, and compared the bridge reinforcement before and after reinforcement load test results, show that the prestressed carbon fiber plate reinforcement can effectively utilize the structural strength of carbon fiber board, improve the bearing capacityofthebridge.
