摘要
通过对加、卸荷应力状态下岩石类材料声发射变化的比较，探讨岩石类材料破坏过程中的声发射现象。在三维应力状态下对岩体模型试样进行三种卸荷破坏试验，依据损伤力学理论对试验结果进行分析，揭示了在工程卸荷作用下岩石类材料的声发射特性。
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.
