The prestressed anchor is anchored in rock, making whole structure to stand against soil press of upside and other load.
预应力锚杆（索）则将此准刚性滑坡体锚固于稳定基岩中，使整个结构抵抗上部传来的土压力和其他附加荷载。

It is a balance system that the anti-slide pile is exerted by three kinds of force, they are the tensile force of anchor, the thrust of sliding mass, the resistance of soil and rock.
The corrosion principle of anchor bolt was analyzed, and the engineering protection measures adopted in rock and soil reinforcement process for the anchor bolt were also discussed.
