Abstract: This paper puts forward the structure theory of the ‘deep slot and anchor hole’ by studies on the anchor bundle bolting part of the surface hole pre-stress gate frusta in Ankang waterpower-station.The method can save 50% quantities of anchor bundles in contrast to original scheme.In addition,the construction is more convenient.It provides the conditions for generating electricity ahead of schedule.

Key words: pre-stress gate frusta, deep slot, anchor bundle

摘要： 笔者以安康水电站表孔预应力闸墩为实例,对锚索锚固部位进行了研究,提出"深槽+锚孔"结构,较原设计方案节省约50%锚索,同时方便了施工,为提前发电创造了条件.
