摘要
拉索是斜拉桥的关键构件,承受桥梁的全部荷载,在风(雨)等作用下容易产生大幅振动。该文介绍了拉索的常见振动及其振动机理,拉索振动控制措施与技术,对斜拉桥拉索振动与减振问题具有一定的参考作用。
The stay cable is a key component of the cable-stayed bridge, witch bears the whole load of the bridge, and large width of the vibration is easy produced under the actions of wind and rain. The article introduces the common vibration of the stay cable and its vibration mechanism, and describes the measures and technology to control the vibration of the stay cable, which have some references for the vibration and damping problems of the cable-stayed bridge.
