Jiangxi Province Tai (and)-Gan (state) highway is in the mountainous and hilly area, in which there is a section of high slope maximum excavation of up to 98 m. Geological conditions for the whole weathering ~ strong weathering granite, was a fractured structure, is very easy to produce the phenomenon of slumping, sliding, etc., affecting the stability of slopes. In view of the engineering geological conditions of this section of the graben slope, the design of the comprehensive consideration of the use of pre-stressing anchor cable reinforcement program. In this paper, through the engineering practice of prestressing anchors in the high and steep road graben slope and geological conditions under the application of the construction of the key points, methods, monitoring and measuring and attention to such aspects as elaborated!
