预应力锚索在公路边坡支护中的应用

REINFORCING HIGHWAY SLOPES BY THE PRE-STRESSED-ANCHORED CABLE

随着高等级公路的出现及山区高速公路的大量建设,公路边坡问题日益突出,预应力锚索加固技术作为一项新兴技术,在公路边坡支护中有着广阔应用前景。本文根据国内外诸多的设计施工实践,综合论述了预应力锚索结构构造和原理、设计、施工原则和施工监测,应用效果和优越性,对有关理论、工艺问题进行了探讨,为进一步推广这些新技术提供了理论参考和实践经验。

With the development of the mountainous express highway, problems of the stability of highway slopes become more important and decisive. As a new technology developed recently, the pre-stressed-anchored cable will be widely adopted to reinforce the highway slopes. Referenced numerous slope cases either in domestic or abroad, the pre-stressed-anchored cables structure, reinforcing mechanism, designing and constructing process, monitoring and evaluating method are introduced in this paper. Then, with a case study, some related theories and their execution works are discussed to serve the technique＇s popularization.
