摘要
对松软 (破碎) 岩层进行分类, 并对其围岩变形、破坏机理以及对巷道支护关系进行分析, 提出流变岩体、弹塑性变形膨胀碎胀岩体、高地应力碎胀岩体中巷道支护的方式, 对松软(破碎) 岩层巷道支护有一定参考价值。
Based on the classification of soft and cracked rock and analysis on the wall rock deformation, destructive discipline and roadway-setting methods, this paper has put forward the setting methods in the roadways with the characteristic of mobile deformation rock, flexible-deforming and expanded clastic rock and strong crustal stress to contribute to the soft and cracked rock formation tunnel-setting.
