This invention discloses a method for evaluating the anti-sliding stability of transmission tower pile foundations on slopes under rainfall conditions. The method decomposes the stability evaluation problem of transmission tower foundations under rainfall-induced landslide conditions into several sub-problems: First, the basic parameters of the slope and future rainfall information released by the meteorological station are obtained to determine the shear strength parameters of the slope soil after rainfall time t. Based on these parameters, a numerical method is used to determine the stability state of the slope. If the slope is unstable, the relative position of the foundation and the potential sliding surface is first determined. If the foundation is above the potential sliding surface, the transmission tower will fail. If the foundation is partially below the potential sliding surface, the rotation angle of the foundation is calculated based on the soil conditions at the bottom of the foundation. The stability of the transmission tower is then determined according to the maximum allowable tilt value of the transmission tower specified in the "Operation Regulations for Overhead Transmission Lines".
