Study On The Steel Tower And The Foundation Design Approaches In Coastal Marsh Area

According to the 500kV Lvsi power station to the eastern Nantong station pow er transmission line design project, this paper discusses about the steel tower and t he foundation design approaches in coastal marsh area, which includes trolley wire steel tower design, basic trolley wire design and antisepsis.As an important sector in power design, transmission and transformation line d esign in coastal marsh area can be related to disciplines such as electrics, mechanis m, electrochemistry, geology, and aerograph. By describing regulations, design thoug hts, and computerization in design process, this paper introduces major problems in iron tower and foundation of transmission and transformation line, and provides a practical design approach. Aiming at the special area-coastal marsh area, combinin g the latest research results and current design experiences both at home and abroa d, this paper develops a approach of steel tower, foundation, and antisepsis design i n coastal marsh area. This approach is economical and practical, and has been impl emented in some places.
