摘要：
Wind tunnel experiments were conducted with stationary and vibrating models whose cross sections were similar to those of some ice formations observed. Aerodynamic data established for iced cables were introduced into the analysis of the whole guyed tower. The quasi-study theory of galloping instability was extended to this end. It was found that the energy input generated by galloping of one cable can be sufficient to cause large amplitudes of the whole tower even at low wind speeds.
