Abstract The invention relates to a method for reducing the ground resistance of a transmission tower foundation, which is characterized in that an original foundation base arranged below the soil surface and an original foundation main column arranged on the original foundation base are included, an original foundation reinforcement cage is arranged on the original foundation main column, the periphery of the original foundation main column is provided with a reamed hole from the soil surface to the original foundation base, and the reamed hole is communicated with the original foundation base. The expanded hole forms an annular cavity, a post-added longitudinal bar and a post-added stirrup hooped on the post-added longitudinal bar are arranged in the annular cavity, and conductive concrete is cast in the annular cavity; the method is suitable for power transmission or distribution line foundation grounding transformation in regions with frequent thunderstorm or regions with large geological soil resistivity; the met
