| 摘 要： | 斜拉索是斜拉桥的主要承载部件，斜拉桥桥跨结构的重量和桥上活载绝大部分或全部通过斜拉索传递到索塔上，实时监测分布于大桥上的桥索张力变化，对于了解斜拉桥的健康状态，确保斜拉桥的安全是至关重要的。采用聚偏二氟乙烯（Polyvinylidene Fluoride）通过监测应变得到拉索的振动信号，计算出拉索的张力，实现斜拉索张力的在线测量。

| Abstract: | The stayed cable of cable-stayed bridges is the main load-bearing components.Most of the load is transfer to the tower of the bridge.Through monitoring the cable tension and its variation,the overall technical condition to a cable-stayed bridge can be estimated and assure the safety of the bridge.Polyvinylidene fluoride is applied as sensor to monitoring the vibration of stayed cables,and the tension of stayed-cable can be calculated to realized the on line measurement of cable-stayed bridges. |
