摘　　要：采用预应力技术加固桥梁结构是目前公认的有效方法,而CFRP板施加预应力的加固技术解决了张拉和锚固技术问题的同时又具有极佳的加固效果。针对采用CFRP预应力板加固的桥梁进行了加固前后结构性能的监测和对比,验证了CFRP预应力板加固效果。相关桥梁加固方案和静载试验过程可供类似工程参考。Prestressing technology is the acknowledged effective method to strengthen bridge structures.The prestressed CFRP plate has excellent reinforcement effect after solving the technical problems of stretch and anchorage.In this paper,the structural performance of the bridge reinforced with prestressed CFRP plate is monitored and compared before and after the reinforcement.The relevant bridge reinforcement scheme and static load test process can be used as reference for similar projects.
