Abstract: Coastal areas frequently experience strong wind disasters, posing a serious threat to the safety of transmission line towers. Scientific tower planning is a key prerequisite for ensuring the stable operation of the power grid. This paper constructs a tower planning model for coastal high-wind regions based on the environmental characteristics, considering four dimensions: basic data collection, wind load calculation, structural selection optimization, and risk assessment. The accuracy of the model is enhanced by combining principles of fluid mechanics and structural mechanics. On this basis, targeted optimization suggestions are proposed in terms of site selection, structural design, anti-corrosion protection, and monitoring and early warning, providing theoretical references for academic research and practical guidance for engineering personnel in actual planning work.
