Study on Pole Foundation Type Selection of 750 kV Transmission Lines in Plateau Area
With the continuous promotion of China's Northwest Development Strategy,the voltage grade of transmission line in northwest China has become higher and higher.Survey on pole foundation type selection for transmission lines in plateau area there is of great significance to construction,operation and maintenance of high voltage grade projects.Based on the foundation design of 750 kV transmission line project in Qinghai province,the foundation type selection under four different foundation conditions,such as thin overburden rock foundation,thick overburden rock foundation,general soil foundation and river network foundation,is studied and analyzed.
