路堑失稳高边坡治理中的锚索动态施工及变形监测

高速公路路堑高边坡在建设期后期发生失稳后,受建设周期和地质勘察条件的限制,基于经验和工程类比的加固方案无法满足实际的要求。本文以岩溶区域某高速公路失稳高边坡为例,介绍了利用变形监测、锚索钻孔等手段获得的信息,对锚索进行动态施工并及时有效地治理了失稳边坡的实例。

Deformation Monitoring and Construction of Anchor Ropes in reinforcing a Unstable High Cutting-Slope

Some freeway high cutting-slopes will lose their stability in late phase of the construction process.Owing to limitation of construction time and geological exploration,it is impossible to accord with factual condition for a primary plan to be designed about reinforcing these slopes,based on experience and engineering analogy.This paper introduces an example about the construction of pre-stress anchor ropes to reinforce a high unstable slope of a freeway effectively and duly in a karst area,according to information from deformation monitoring and anchor rope drilling.
