摘要
基于锚杆支护作用原理和锚杆工作载荷的动态无损测试技术,通过大型相似模拟实验,论述了锚杆工作载荷和围岩表面位移的相关关系,得出围岩变形破坏的各个阶段和锚杆工作载荷变化的对应关系,从而达到通过锚杆工作载荷的无损检测来实时评估巷道的稳定性。
Based on the mechanism of bolt timbering and nondestructive testing technology of bolt working load, through simulation experiment , the correlativity of working load of bolt and displacement of surrounding rock is obtained .The correlativity of distortion of surrounding rock and changing of working load of bolt is introduced .So the stability of surrounding rock can be valued by nondestructive testing of bolt working load.
