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。 In the construction of expressways, railways and reservoirs in mountainous areas with large natural slopes, in order to reduce the disturbance to the mountain, prestressed anchor cables are often used to reinforce the mountainous dangerous rock within the scope of the newly built project. This treatment method has the input Less, easy to environmental protection, maneuverability and other advantages. However, during construction, the design intent must be fully understood, the dangerous rock mass to be reinforced should be investigated in detail, and the construction parameters should be adjusted according to the specific conditions to ensure that the cable system is reasonably loaded.
