| 摘 要： | 崩滑体是三峡库区奉节、巫山、巴东等地较为普遍的地质现象，具有厚度大、风化破碎等特征，是三峡库区地质灾害治理的主要对象, 锚固是崩滑体治理的手段之一。本文通过分析崩滑体的地质特征及全长粘结锚杆的作用机理，结合三峡库区一大型崩滑体治理工程，说明采用全长粘结锚杆不仅增加了坡体的抗滑力，而且通过锚杆的植入改善了坡体的结构性，从而提高崩滑体的稳定性。

| Abstract: | 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. |
