预应力锚索在垮岩山危岩治理工程的应用

APPLICATION OF THE PRESTRESSING FORCE ANCHORED CABLE TECHNIQUE TO HARNESSING OF THE KUAYANSHAN UNSTABLE ROCK

预应力锚索技术广泛运用于公路、铁路、水电站、矿山井巷、隧道工程、地质灾害等永久性边坡加固,施工技术日趋完善。该方法具有造价低、工期短,施工便捷等优点。本文以预应力锚索施工技术在垮岩山危岩灾害治理中的成功实例,介绍了危岩发育地质环境条件、治理方案、施工工艺,总结了施工经验,对同类工程具有参考价值。

The prestressing force anchored cable technique has been widely used in permanence slop strengthening in highway, railway, hydropower station, mine workings, tunnel workings, and geologic hazard. The technique has such specific characters ： a low cost, and a short construction time so that it is a facile construction technique. Through the successful instance of the prestressing force anchored cable technique using in harnessing Kuayanshan unstable rock, this paper introduces the unstable rock geological environmental conditions, treatment plan, construction, technology, and summarizes successful construction experience, which has reference value to similar works.
