摘要
利用超声波技术对不同水灰比的混凝土立方体的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。研究表明,超声法能够综合反映混凝土内部裂缝的扩展规律,有利于混凝土的损伤力学机理研究。
The damage characteristics of concrete,which include those of cube and prism specimens with different W/C ratios,are studied by ultrasonic technique.The relations between the changing trends of acoustic parameters and the evolvement of damage in the process of loading are discussed.Experiments show that ultrasonic technique is able to reflect the trends of propagation of cracks in concrete,and is of benefit to studying the damage mechanics of concrete.
