【摘要】 对于采用锚喷支护的岩石巷道，依据弹塑性小变形理论，提出应对支护结构进行概率极限状态优化，利用蒙特卡络方法，建立了巷道围岩稳定、锚喷支护结构的可靠性计算公式，从而为巷道围岩稳定性评估，支护设计提供可靠的理论依据。更多还原

【Abstract】 For bolting and shotcrete lining roadways,according to the elastic-plastic and small deformation theory,the probabilistic limit state of supporting structure should be eptimized.Using improved Monte Carlo method ,this paper derives the reliability Computing formula of bolting and shotcrete lining structure and surrounding rock stability and Provides a reliable theoretic basis for Stability eraluation and Supporting design of underground roadways.更多还原
