摘　　要：在山体自然坡度较大的山区修建高速公路、铁路及水库大坝时,为了减少对山体的扰动,经常采用预应力锚索对新建工程范围内的山体危岩进行加固,这种处理方法具有投入少、便于环保、可操作性强等优点。但施工时必须充分理解设计意图,详细勘察好待加固的山体危岩,根据具体情况调整好施工参数,确保锚索体系受力合理。Natural slope is bigger in the massif when mountain area builds the express highway, railroad and reservoir dam, The perturbation motion for falling off to the massif, the dangerous rock of massif go along strengthening often adopt the face to face new-built project of prestressing force anchorage cable range inner. The method this is handled is had throwing into few, easy to environmental protection, operatability waiting for merit by force. But be obhged to sufficient make of designs intention when being under construction, surronding rock surveying the massif easy to wait for strengthening detailedly, adjust the parameter easy to be under construction as the ease may be, ensure anchorage cable system to accept force reasonableness.
