摘要
为了研究独塔斜拉桥的动态特性，用来回跳车、风、锤击等方法测试了系统的自振频率，并进行了综合分析；用锤击法得到系统的传递函数，用动态分析仪进行数据处理获得了系统的各阶阻尼比和振型。并对整桥的动态特性进行了评价。
Dynamical characters of the cable-stayed bridge with single tower are considered by the experimental method. Natural frequencies of the bridge are obtained by the shock, wind excitation and hammering method and these experimental techniques are compared. Damping ratios and vibration model of the system are analyzed by the transfer function method. The vibration character of the bridge is evaluated.
