摘　　要：以预应力锚索为研究对象,结合云南省某边坡工程实例,对普通拉力型、拉力分散型、拉压复合型及压力分散型四种锚索进行张拉试验测试。找出锚索钢绞线的应力应变分布规律、钢绞线荷载~孔深分布规律,为合理选择锚索类型提供依据。In this paper,prestressed anchor cable was focused.Combining with a slope engineering case,tension experiments of four anchor cables were carried out,such as general tension-type,tension dispersed-type,tension and compression compound-type and compression dispersed-type.The distributed laws of stress-strain and steel strand load to hole-depth of anchor cable were deduced.These conclusions can provide reference for selecting anchor cable rationally.
