摘要: 锚固工程技术通过在锚孔底部注射水泥砂浆,将锚杆、砂浆及周围岩土体形成锚固体,锚固体与周围岩土体在外力作用下将产生摩擦力,提供一个反作用力。预应力锚杆通过在孔口施加外力,利用摩擦力与反作用力的相互作用对边坡进行预加固,从而保证边坡的稳定性。通过介绍预应力锚杆的设计原理、施工工艺及施工质量检测,说明了预应力锚杆在高边坡防护加固中应用是行之有效的。

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
