The invention discloses an anti-tilt foundation for an electric tower. The anti-tilt foundation for the electric tower comprises an installation foundation, a support foundation, an installation block fixed to the top of the support foundation, and an adjusting shell; an annular limiting board is arranged on the side face of the installation foundation; a transversely-arranged left hollow chamber and a transversely-arranged right hollow chamber are arranged inside the installation foundation; a rectangular piston is arranged inside each hollow chamber; two sets of parallel adjusting rods are fixed to the upper surfaces of the rectangular pistons; a limiting column is fixed to the center of the lower surface of each rectangular piston; the adjusting rods penetrate through the installation foundation; and a spherical head is fixed to the end, outside the installation foundation, of each adjusting rod. After the anti-tilt foundation for the electric tower is fixedly installed, when the electric tower tilts due to uneven stress, the support foundation can change the support angle by pressurizing the tilted position, and accordingly the electric tower is effectively maintained, and the effective use time of the electric tower is prolonged.
