预应力锚索是由钻孔穿过软弱岩层或滑动面,把一端(锚杆)锚固在坚硬的岩层中(称内锚头),然后在另一个自由端(称外锚头)进行张拉,从而对岩层施加压力对不稳定岩体进行锚固处理方法。预应力锚索施工属于可承受拉力的结构性系统,是在基础高边坡支护工程中的一种重要的边坡支护技术。高边坡预应力锚索施工技术可以主动对被加固的岩土体施加有效的压应力,使得岩土体发挥自身的自承潜力,进而起到提高岩土体的强度以及稳定性,控制支护结构出现过大变形或者位移等质量问题。
Prestressed anchor cable is drilled through the weak rock or sliding surface, one end (anchor) anchored in a hard rock (called anchor), and then at the other free end , So as to exert pressure on the rock to instabilize the rock mass for anchoring treatment. Prestressed anchor cable construction belongs to the structural system that can bear the tension and is an important slope support technology in the foundation high slope support engineering. The prestressed anchor cable construction technology of high slope can take the initiative to exert effective compressive stress on the reinforced rock and soil so that the rock and soil can exert their own self-supporting potential, and then improve the strength and stability of rock and soil, Protection structure appears excessive deformation or displacement and other quality problems.
