摘要: 以地下开采锚固工程中使用较为普遍的715.24 mm锚束为原型,在贵州开磷马路坪中深部(+640~+700 m中段)的采场进行现场试验,进行了多根普通预应力锚索的拉拔破坏试验,得到了每根岩锚的荷载变位曲线、失效破坏模式和锚固段长度、锚索网度、岩石强度等各种因素对预应力锚索锚固性能的对比分析结论,为马路坪矿井下支护工程提供了可靠的试验依据。

Abstract: Anchoring through the use of underground mining, which is more common 715.24 mm anchor beam as the prototype, Multiple ordinary prestressed cable pullout failure test was conducted in deep (+640 ~ +700 m the middle) of the Maluping mining field test site. Comparative analysis findings of Each rock bolt load deflection curve, failure mode and failure of anchorage length、cable network rock strength and other factors on the performance were obtained. It provides a reliable experimental basis of Underground Support Project for Maluping mine.

Key words: Prestressed anchor, Side resistance testing
