Abstract: The ground anchor is a technique that injecting the cementsand slurry in a small diameter borehole and grouting the ground anchor and surrounding soils so that the reaction can be provided throughout the grouted body. The prestressed ground anchor is a technique of providing a prestress at the top of the borehole in stabilizing the slope. This paper presents the principal aspects of the prestressed ground anchor design, construction and quality control as well as quality assurance.

Key words: Prestressed Ground Anchors, High Slopes, Stability Improvement
