针对巷(隧)道围岩物理、力学及环境参数取值的不确定性及现有岩爆预测方法的局限性与不足,考虑围岩岩爆的特点,引入区间分析理论,给出巷(隧)道围岩稳定非概率可靠性分析的区间运算方法;视巷(隧)道围岩物理、力学及环境参数为区间变量,根据岩爆烈度分级标准,建立基于区间理论的高应力巷(隧)道围岩岩爆、岩爆烈度分级的非概率可靠性预测模型;通过工程实例分析,结果表明了本文方法的合理性与可行性,并探讨了各参数离差的变化对非概率可靠性指标的影响规律,具有一定的工程参考价值.
In view of the uncertainty of the physical, mechanical and environmental parameters of surrounding rocks in laneways and tunnels and the limitations and shortcomings of the existing rockburst prediction methods, considering the characteristics of rock burst in surrounding rocks, by introducing the theory of interval analysis, Tunnel), the physical, mechanical and environmental parameters of surrounding rock are used as interval variables. Based on the grading criteria of rockburst intensity, a high-stress alley based on interval theory is established Tunnel) road rock burst, rockburst intensity classification of non-probabilistic reliability prediction model; through the engineering example analysis, the results show that the method of this paper is reasonable and feasible, and discusses the variation of the various parameters of non-probabilistic and reliable The impact of sexual indicators, with some engineering reference value.
