Large-scale loose sediment is the main geological hazard which should be treated at Fengjie

Wushan and Badong counties in the Three Gorges Reservoir area. Ground anchorage is one of the treatment method. In this paper the geological property of large-scale loose sediment and the mechanism of wholly grouted anchor are studied. The application of wholly grouted anchor in the treatment of a large-scale loose sediment in the Three Gorges Reservoir area is presented to show that the grouted anchors not only increase the sliding friction of the slope body

but also improve the constructive property of the slope body by sewing the loose party of slope through the friction distributing along the whole bar. The results indicate that the sliding stability of large-scale loose sediment can be greatly improved by using wholly grouted anchor.
