CFRP板加固病害桥梁的术后监测系统

Postoperative Monitoring System of CFRP Plate Strengthening Diseased Bridges

摘要: CFRP具有轻质高强、耐腐蚀、抗疲劳性能好的特点，是一种加固病害桥梁优异材料，随着我国交通运输运力的快速增长，不同等级公路上的行车密度也日益增加，这使得很多的既有公路桥梁已经无法满足交通运输的需求。对既有桥梁结构进行安全状态评估和实时健康监测迫在眉睫。CFRP板加固病害桥梁的术后监测系统是将目前比较流行的预应力碳纤维板体外预应力加固法和桥梁健康监测系统结合起来，一次性解决病害桥梁的加固与监测问题。为桥梁戴上“智能健康手环”，从而实现对桥梁的实时监测。

Abstract: CFRP is an excellent material for strengthening diseased bridges, which is characterized by light weight, high strength, corrosion resistance and good fatigue resistance. With the rapid growth of transportation capacity in China, the traffic density on highways of different grades is also increas-ing, which makes many existing highway bridges unable to meet the needs of transportation. It is urgent to evaluate the safety status and monitor the real-time health of existing bridge structures. The postoperative monitoring system for strengthening diseased bridges with CFRP plates com-bines the currently popular external prestressing method of prestressed carbon fiber sheets with the bridge health monitoring system to solve the problem of strengthening and monitoring dis-eased bridges at one time. Put on the “smart health bracelet” for the bridge, so as to realize the re-al-time monitoring of the bridge.
