| 摘 要： | 三峡库区滑坡治理工程采用锚杆格构、挡土墙、抗滑桩等综合治理方案。为增加滑坡体的稳定性，在抗滑桩的顶部施工超深预应力锚索，增加滑移带的法向应力，对滑坡体的稳定性至关重要。主要介绍了超深预应力锚索施工方法、锚索成孔技术、灌浆施工及张拉施工。

| Abstract: | Comprehensive treatment with anchor lattice, retaining wall and anti-slide pile was adopted for landslide control project in Three Gorges Reservoir. In order to increase the slide stability, it is important to construct the ultra-deep prestressed anchoring cable at top end of the anti-slide pile and increase the normal stress of slip band. The paper introduced the construction of ultra-deep pre-stressed anchoring cable, borehole for anchor cable, grouting and tension construction. |
