Research on the Rock Acoustic Emission Rules under Different Experimental Conditions

Article Preview

Abstract:

The damage process is accompanied by the acoustic emission (AE) for brittle materials such as rocks. An AE experimental research was investigated based on different loading velocity, moisture content and rock structure. The research shows that Increasing loading velocity makes the duration of obvious AE longer, average AE rate improved, the strain values of obvious AE decreased; More moisture content delays the time of obvious AE, reduces the values of AE, increases the strain values of obvious AE; inferior structure rock has little AE, and appears discretely; The main reason of AE difference is the different rock structure.
