PROBLEM TO BE SOLVED: To provide an inverted T-shape foundation having excellent pull supporting force property, its constructing method, and a power transmission steel tower system.;SOLUTION: The inverted T-shape foundation comprises a floor plate part for storing the root front ends of a tower leg materials, and a column body part provided on the upper face of the floor plate part for supporting the roots of the tower leg materials, wherein a haunch is formed at the outer peripheral edge on the upper face of the floor plate part where the column body part is provided. The deepest lower end of the haunch is located on the opposite side of the shallowest lower end of the haunch. The enlarged bottom angle of the deepest lower end of the haunch is the maximum, and the enlarged bottom angle of the shallowest lower end of the haunch is the minimum. The enlarged bottom angle becomes gradually smaller as tending from the deepest lower end of the haunch to the shallowest lower end of the haunch.;COPYRIGHT: (C)2009,JPO&INPIT
