摘　　要：高发射塔受到风荷载的影响较大,而且风荷载具有随机性、高能量和高破坏性的特征,为保障发射塔的安全必须在建设时做好抗震动处理。河南省广播电视发射塔建设高度为388m,并且在塔楼设置有观景旋转平台,为了舒适度,对观景旋转平台提出了较高的抗震动要求。2009年,河南省广播电视发射塔建设完成后,我们一直观察发射塔震动情况,到目前为止,抗震动性能良好,达到设计要求。The high launching tower is influenced easily by wind load, and the wind load has characteristics of randomness, high energy and high destruction. In order to protect the launching tower, the seismic disposal should be done in the construction. The height of Henan Radio and TV tower is 388 meters. On the tower, there is a rotating viewing platform. In order to comfort, there is a higher requirement for anti vibration. In 2009,after the completion of the construction of radio and TV tower, we have been watching the shock situation, so far, the perfornlance of anti- vibration is good, meet the design requirement.
