摘　　要：北部湾滨海滩涂高压输电线路铁塔基础受损实例表明,基础区域的海水流速越高的基础受损越严重;根据杆塔基础区域的潮汐海水流特点,可采用钢护筒护壁、临时性或永久性围堰等防冲刷措施来减轻或消除海水对基础的水流磨损。Taking the tower foundation damage of HV transmission line at coastal tidal flat of Beibu gulf as example,it is indicated that the faster the seawater flows,the severer the foundation damages.Based on the characteristics of tidal flow at tower foundation area,some anti-scouring measures can be taken to protect foundations away from erosive wear and corrosion of seawater tidal flow,such as steel protecting sleeve,temporary or permanent cofferdams etc.
