摘　　要：垫板角度关系着锚索的锚固角度,对于预应力锚索的锚固性能非常关键。为了使锚垫板能匹配不同钻孔角度的锚索,论文设计了可调角度垫板,并通过有限元分析计算和现场试验的方式对其适用性和承载力进行研究,完善设计并指导施工。The angle of the plate is related to the anchoring angle of the cable,which is very important for the anchoring performance of the prestressed cable.In order to make the anchor pad can match the anchor cable of different drilling angles,this paper designed the adjustable angle cushion plate,and through finite element analysis and calculation and field test to studyits applicabilityand bearing capacity,improve the designandguide the construction.
