钢管混凝土系杆拱桥吊杆索力检测

Detection of Suspender Cable Force of a Concrete Filled Steel Tubular Tied Arch Bridge

通过对某运营中钢管混凝土系杆拱桥进行建模分析,并在恒载情况下对该桥梁吊杆索力进行测试,测试方法选用振动频率法,对该方法的原理及应用进行进一步讨论。计算出本桥测试索力与成桥索力并进行比对,得出结论,为该桥梁吊杆的维修加固提供依据。

By modeling and analyzing a concrete-filled steel tubular tied arch in operation, and testing the suspender cable force of the bridge under dead load, the vibration frequency method is selected as the test method, and the principle and application of this method are further discussed. The test cable force of the bridge is calculated and compared with the completed cable force, and a conclusion is drawn, which provides a basis for the maintenance and reinforcement of the suspender of the bridge.
