Study on techniques of applying vertically prestressed anchor retaining wall to treat landslide

The occurrence and the development mechanism of one small landslide in the Fu-Chang road at the Taihang mountain is analysed with the comprehensive exploration methods such as engineering geophysical prospecting and geological prospecting etc.. It is brought forward that the small landslide is a shallow layer crushed stone slide with the type of drawing – enlarging outside. The vertical prestressed anchor retaining wall is applied for correcting the landslide 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. This method reaches the purpose of decreasing the masonry and the engineering price. The design thinking of the vertical prestressed anchor retaining wall is analyzed in detail; the construction technology and technique essentials is introduced. The efficiency of the method is indicated by its well correction result. This technique can offer reference for the similar geological disaster correction.
