The Selection Of Foundation Type Of Large Cross-Section Wire Of Transmission Line Iron Tower In Mountain Areas

摘要

For difference of elevation of transmission line in mountain areas, special considerations are needed for foundation design and construction. Take double-loop wire of 2×400 and mixed voltage four-loop wire of 2×630 iron tower as analysis examples, material quantity and economy index of different types of foundation in mountain areas are analysed in this paper so as to provide inference information for electrical construction.
