摘要
通过砂岩的损伤声发射试验,分析了砂岩损伤各个过程的声发射特性,发现在岩石损伤的各个过程中,其声发射表现出不同特性,特别是岩石在破坏之前,声发射会有一个稳定期,这对利用声发射监测岩石的破坏具有现实意义。
Through acoustic emission test on damage of sandstone, the characteristics of acoustic emission in stages during damage course of sandstone are analyzed. It is found that during the various stages of the damage, the acoustic emission shows different characteristics; especially before rock is broken, acoustic emission has a stable stage, which has realistic meaning to use of acoustic emission for supervision of rock breaking.
