预应力锚索在公路高陡边坡加固整治工程中的应用

Application of Pre-stressed Cable Bolt in the Reinforcement Construction of High Slope of the Expressway

摘要:

预应力锚索锚固技术以其结构合理、工艺灵巧、适应性广、施工速度快、造价低等优势，目前已广泛应用于各工程领域。在桂（林）—柳（州）高速公路高边坡加固工程中采用了该项技术，经过近1年的运转表明，效果良好。对该项工程作了详细讨论，介绍了边坡的地质条件、稳定性分析和设计参数的选取，总结了施工中锚索的造孔、下索、注浆、张拉锁定等设计及施工要点。

Abstract:

With the advantages of reasonable structure, handy workmanship, wide adaptability, speedy construction and small cost, the technology of pre-stressed cable bolt has been used in various engineering construction. Good result is proved in a running year. The geological condition and stability analysis of the slope as well as the parameter design are introduced; the experience is summarized in the design and the construction procedure, which include drilling, putting cable, grouting, and tension locking.
