To study the transient response characteristics of wind turbine structures-extended foundations under wind loads in mountainous areas, this paper develops a simplified analytical model based on soil-structure interaction theory. It explores the effects of constraint conditions, wind speed, and foundation shear wave speed on the transient response behavior. By analyzing the time-domain and frequency-domain trends of tower top displacement, foundation horizontal displacement, and foundation rotation angle, the relationship between foundation shear wave speed and the safe wind speed of the wind t...
