SF-1型岩石声发射测试仪是岩石力学实验研究的一种非常有用的测试仪器。它可以用来监测岩石或岩石样品在外力作用下,发生变化过程中由微破裂所产生的声发射现象。它不仅可以研究微破裂与应力、变形、波速、时间等的变化规律,而且还可以进一步研究微破裂与主破裂(大破裂)的关系。所以它在岩石或岩体的变形破坏实验研究中具有重要的意义。多年来,在进行岩石力学研究中一直缺少适用的声发射仪,从而影响了这方面工作的开展。为了当前 SF-1 Rock Acoustic Emission Tester is a very useful test instrument for rock mechanics experiments. It can be used to monitor acoustic emission from micro-fractures of rock or rock samples under external forces. It not only can study the variation law of micro-fracture, stress, deformation, wave velocity and time, but also can further study the relationship between micro-fracture and main fracture (big fracture). Therefore, it is of great significance in the experimental research on deformation and failure of rock or rock mass. Over the years, there has been a lack of suitable acoustic emitters in rock mechanics research, which has affected the work in this area. For the moment
