Abstract: To support the revision of DL/T 5219-2014, by sorting out the history evolution of the foundation safety factor of the relevant regulations and standards, and distinguishing different foundation types such as gravity foundation, drilled shaft foundation, rock anchor foundation, pile foundation, rock-socketed pile different foundation types, the value of the foundation safety factor of transmission lines was studied, and some suggestions for the revision of the foundation safety factor are given. The results show that the double safety factor method which is related to soil resistance and different safety factor which is related to the dead weight of foundation should be adopted in the uplift calculation. It is recommended to distinguish the safety factor based on the foundation type and value the factor based on the depth of the foundation for compression calculation. The results can be used as reference for the revision of the code DL/T 5219-2014.
