The mechanism of one small slide in the FuChang road at the Taihang mountain is analyzed with the comprehensive exploration methods. It is brought forward that the small slide is a shallow layer crushed stone slide with the type of drawing – enlarging outside. The vertical prestressed anchor retaining earth wall is applied for safety correcting the slide with the economical and feasible correction principle. This method depends on the vertical prestressed force, pressed on the earth wall body which is made by the anchor in the foundation, to balance the sliding force of the slide mass. The design thinking of the vertical prestressed anchor retaining earth wall is analyzed in details and the construction technology and technique essentials is introduced in this paper. The efficiency of the method is indicated by its well correction result.
