框架锚索联合钢花管注浆在堆积体边坡治理中的应用

The Application of Frame Anchorage Combined with Steel Floral Grouting in Treatment of Accumulated Slope

堆积体尤其是深层堆积体在开挖过程中易产生牵引式滑坡,其治理难度较大,很难采用单一的方法进行治理。结合贵州省晴兴高速公路某堆积体边坡,在分析边坡工程地质条件的基础上,提出采用微型钢管桩、框架锚索、钢花灌注浆、路堑墙等多手段加固的设计方法。

Accumulation bodies, especially deep accumulation bodies, are prone to produce traction landslides during excavation. And it is difficult to adopt a single method to govern those slopes. Based on the analysis of the engineering geological conditions of the accumulation slope which is located in the Ginglong Xingyi Expressway of Guizhou Province,the strengthening design method of the micro steel pipe pile, the frame anchorage cable, the steel floral grouting and the cutting wallis puts for ward.
