| Abstract: | By comparing the change of acoustic emission of rock materials under loading and unloading conditions, acoustic emission phenomenon has been discussed during the damage process of rock materials. Under three dimensional stresses states,the rock mass model specimens have been experimented with threekinds of unloading ways. According to the damage mechanics theory,experimental results have been analyzed .Acoustic emission character of rock materials has been revealed under engineering unloading conditions. |

| Keywords: | rock materials stress states acoustic emission. |
