摘要
利用超声波技术对不同水灰比的混凝土立方体试块和棱柱体试块的损伤特性进行了试验研究,讨论了加载过程中声学参数变化与混凝土损伤演化规律之间的关系。试验研究表明,超声法能够比较全面反映混凝土内部裂缝的扩展规律,有利于进一步研究混凝土的损伤力学机理。
The damage characteristics of cube and prism concrete specimens with different W/C ratios are studied by ultrasonic technology in this paper. The relations between the changing trends of acoustic parameters and the evolvement of damage during the process of loading are discussed. Experiments show that ultrasonic technique can reflect the trends of propagation of cracks in concrete and help to study the damage mechanical properties of concrete.
