摘要
声发射技术是应用较为广泛的一种无损检测技术;论述了声发射在混凝土力学行为中的应用。围绕声发射在混凝土断裂机理、混凝土损伤定位、声发射参数与腐蚀钢筋混凝土的关系、声发射在粘结滑移中的应用、声发射在疲劳荷载作用下的反应、混凝土结构损伤评估等展开讨论,归纳出国内外混凝土结构声发射研究现状,阐述了混凝土声发射技术有待深入探讨的问题。
Acoustic emission is a widely used non-destructive testing technology. The application of acoustic emission in the study of mechanical behaviors of concrete is discussed. It focuses on the following aspects： the mechanism of concrete fracture,the damage location,the relationship between acoustic emission parameters and corrosion of reinforced concrete,the bond-slip behavior between rebar and concrete,behavior under fatigue load,the damage assessment of concrete structure and so on. The state of the art of researches is summarized. The problems to be solved in specific areas are discussed.
