摘　　要：采用环境随机激振方法对江阴500kV输电线路的一座拉线塔和自立塔分别进行了实测。得到了拉线塔横向、纵向及扭转向的一阶频率、振形和阻尼比。并对自立塔和拉线塔的实测结果进行了比较。Taking JiangYin 500 kV transmission system as the case study, including a self-support transmission tower and a guyed transmission tower, the on site dynamic vibration measurement is made, which is excited by the random environment micro-quiver. Also , the first mode of the two towers are obtained including the frequencies , the flutter states , and the damping ratios. In the end, the results of the measurement are compared between the two towers.
