摘要
实践表明 ,锚杆支护具有技术先进、经济合理、安全可靠等优点而被广泛地推广应用 ,但有时也存在设计不合理 ,支护强度大 ,支护费用高 ;或支护强度不足 ,安全性差的情况。通过对大断面巷道锚杆支护设计方法、参数、施工工艺、稳定性监测和经济效益等方面的研究 ,为类似条件下锚杆支护提供了借鉴。
Practice indicated that bolting technology had advantages of advancement,economic reasonableness,safety and reliability,and therefore it was extensively spread and applied.However,it also had disadvantages of unreasonableness in design,great shoring intensity and high cost,or inadequate shoring intensity and poor safety,etc..Through researches into design methods of bolting technology on large section in tunnel,design parameter,construction technology,monitoring of steadiness and economic profits,this paper provides reference for anchor pole shoring under similar conditions.
