一、绪言不仅在回采矿柱及开凿地下贮藏库、地下发电站等大型硐室时需要监测岩体,而且在评价几乎所有岩体中构筑物之稳定性时,它也是必须进行的工作之一。用于监测岩体,有弹性波、微小破裂音[声波辐射(Acoustic emission),略称为AE]和电阻率探测等方法。本文作者从几年前就开始对岩石试样进行刚性压缩破坏性试验,测定了直至试样破坏时的应变变化、弹性波传播速度的变化、弹性波在传播过程中振幅衰减的变化和微小破坏音的发生情况等。通过对这些测定结果的研究,得出了如下结论:通 I. INTRODUCTION It is not only necessary to monitor rock masses when mining pillars and excavating large underground chambers such as underground storage facilities and underground power stations. It is also one of the tasks that must be carried out in evaluating the stability of structures in almost all rock masses. It is used to monitor rock mass, elastic wave, tiny cracked sound (Acoustic emission, abbreviated as AE) and resistivity detection. The authors began rigid compression destructive tests on rock samples from a few years ago. The strain changes until the specimens were destroyed, the propagation velocity of the elastic waves, the amplitude attenuation attenuation and the minor damage of the elastic waves during the propagation The sound of the situation. Through the study of these measurement results, the following conclusions are drawn:
