摘要
基于玻璃钢锚杆在巷道支护中的力学特性以及工程可靠度计算模型,确定了回采巷道顶板和两帮玻璃钢锚杆的支护状态方程和可靠度计算方法。结合金山店铁矿回采巷道的具体支护问题,通过蒙特卡罗直接抽样法计算出玻璃钢锚杆的可靠度为0.9015,满足矿山回采巷道支护工程可靠性要求,为玻璃钢锚杆在金属矿山回采巷道中的应用提供了科学依据。
Reliability analysis is the premise of safety application of GFRP in roadway supporting.Based on engineering reliability calculation model and the mechanical properties for GFRP Bolt on roadway bolt,the equation of state and reliability of calculation methods of GFRP blot for the wall and the roof of roadway are determined.And the reliability of GFRP bolt is calculated to 0.9015 by Monte Carlo directly sampling method,combined with the concrete support on roadway of Jinshandian Iron Mine,meeting the engineering reliability of roadway support in iron mine and providing a scientific basis for GFRP bolt support application in the roadway of iron mine.
