摘　　要：高强度预应力注浆锚索由预应力锚头、多根预应力钢丝、中空注浆管等组成,具有承载强度高、预应力大、注浆方便、端锚与全长锚固相结合等优点,适用于复杂条件矿井、水电站、公路、铁路、以及其他灾害边坡等工程的加固治理中。在深部煤矿井大断面巷道及硐室支护中应用效果较好。Grouting bolting rope with high strength and pre-stress is composed of pre-stress anchor head, multiple pre-stress steel wires and hollow grouting pipe. With the merits of high load-bearing, high pre-stress, convenient grouting and full bolting, this kind of bolting rope is fit for supporting of mines, hydropower station, highway, railway and other slope engineering with complex conditions. It had made better application effect in supporting roadway and cavern with large section in deep coal mine.
