Variable cross-section T-shaped sheet-pile wall structure

The utility model belongs to the technical field of retaining engineering, and particularly discloses a variable cross-section T-shaped sheet-pile wall structure beneficial to reduction of engineering cost. The variable-cross-section T-shaped sheet-pile wall structure comprises at least two slide-resistant piles arranged on a side slope at intervals and a soil retaining plate arranged between any two adjacent slide-resistant piles, and the lower ends of the slide-resistant piles penetrate through a foundation surface and extend into a side slope slide bed; the portion, located above the foundation surface, of the anti-slide pile is the upper portion of the pile body, and the size of the cross section of the upper portion of the pile body is gradually reduced from bottom to top. The upper portion of the pile body is arranged to be of a structure with the cross section size gradually reduced from bottom to top, so that the upper portion of the pile body can be basically consistent with stress changes in the soi
