摘要
金丽温高速公路K81+6 35～K82 +0 0 0路段由于受区域性断层影响 ,左侧边坡岩体非常破碎。路堑的开挖和雨水的侵入诱发了坡体内古滑塌体的滑动 ,给工程带来了极为不利的影响。经过详细的地质勘察和防治方案分析对比 ,最后采用了单孔复合型预应力锚索锚固坡面 。
Because of regional faultage,the fissured rockmass property on left cut side along K81+635～K82+000 section of Jinliwen Expressway is very poor.Furthermore,the cutting and the invasion of rainwater trigger the K81 landslide.To stabilize this slope,particular reconnaissance has been done and several schemes have been referred.After strict selection,a final decision is achieved by a new technique——single bore multiple prestressing anchor method,by which a satisfactory result is obtained.
