At present soil weight method can be used to calculate foundation uplift stability of transmission lines on flat ground.However the gradual increase of transmission lines in mountain areas makes the calculation of uplift stability for transmission lines built on slopes become an urgent engineering problem.Based on the calculation principle of soil weight method on flat ground,this paper deduces an improved uplift stability calculation formula of transmission lines on slopes.By comparative analysis with the case of flat ground,it proposes the slope uplift stability factor and obtains impact and laws of slope condition on uplift stability.The results can be useful reference for foundation uplift stability analysis of transmission lines built on slopes.
