摘　　要：在高边坡开挖及地下洞室、隧道掘进中 ,用锚杆锚固来提高危岩的稳定性 ,开发研制的新型水泥基锚固灌浆材料及水泥基药卷式锚固剂 ,克服了一般常用的水泥机锚固材料固化慢 ,早期强度较低的缺点 ,使用方便 ,在工程应用中取得了较好的经济效益 。In excavation of high slopes and underground tunnels and caverns, anchor bolts are frequently used to increase the stability of fractured rock mass. The newly developed cement base anchoring grout material and cartridge type cement base anchoring agent overcome the defects of conventional cement tying materials which are slow in curing and low in early strength. The new material is easy to use and its application in projects has resulted in great economic benefit, and thus it is worthy of widening application.
