用声发射监测岩石与混凝土界面的破坏过程

The damage process of rock-concrete interface by acoustic emission

利用声发射技术监测岩石与混凝土界面的破坏过程,提取了岩石与混凝土界面不同阶段的声发射信号,研究了应力-应变关系及其与声发射信号的耦合关系。研究表明,声发射信号能有效反映两者界面损伤破坏的演变过程。

Monitor damage process of Rock-concrete by acoustic emission and acoustic emission signal of different destruction states is picked up. At the same time, study the coupling relation between acoustic emission and stress-strain, the experimental results studied that the damage process of Rock-concrete interface can be detected by acoustic emission signal.
