摘要
通过实验室试验和理论分析 ,研究了巷道锚杆支护对锚固范围岩体峰值强度和残余强度的强化作用以及对锚固体峰值强度前后 E,c,φ值等力学参数的改善 。
Based on laboratory tests and theoretical analysis, the enhancing function of bolting support to the peak and residual strength and improvement to the E, c and values before and after peak strength of bolted rocks surrounding roadways are studied. The extent is also discussed to control the plastic and broken zones of surrounding rocks under the bolted action.
