应力波峰值变化与岩体结构关系的试验研究
Experiment Studies on Relationship between Peak Value Change of Stress Wave and Rock Mass Structure
【摘要】 选择了3种有代表性的岩体结构进行冲击试验,分析研究了波形最大峰值变化与岩体结构的关系。试验结果表明:震动峰值随空间衰减、震动峰值延时及其离散性变化均能有效反映岩体结构特点和受扰动程度,也能反映岩体的各向异性。
【Abstract】 Three representative species were chosen for impact tests on rock mass structure.The relationship between variation of peak value and rock mass structure is analyzed and studied.The experiment results indicate that the attenuation of vibration peak value with special distribution,time delay at the vibration peak value and discreteness change,all reflect rock mass structure and interference degree,as well as anisotropy of rock mass.
