摘要:
为验证FUT510超声波探伤仪在混凝土空洞缺陷识别中的可应用性,分别制备1个正常混凝土试件和1个含空洞混凝土试件,利用FUT510超声波探伤仪获得试件的声学参数,分别使用穿透法、平测法识别试件空洞区域;根据声速计算得出试件弹性模量,通过弹性模量变化情况识别出试件空洞。根据声学参数计算得出试件的临界值与异常值识别出混凝土中的空洞大小;通过分析不同龄期声速变化情况计算得出弹性模量的变化趋势,以此识别出混凝土中存在的空洞缺陷。由此证明使用FUT510超声波探伤仪在识别混凝土空洞中有较强的应用性。
Abstract:
In order to verify the applicability of FUT510 ultrasonic flaw detector in the identification of concrete cavity defects,this paper prepared a normal concrete specimen and a concrete specimen with cavity,obtained the acoustic parameters of the specimen using FUT510 ultrasonic flaw detector, and identified the cavity area of the specimen using penetration method and horizontal measurement method respectively.The elastic modulus of the specimen is calculated according to the sound velocity, and the cavity of the specimen is identified by the change of the elastic modulus.The critical value and outlier value of the specimen were calculated according to the acoustic parameters to identify the size of the cavity in the concrete.The change trend of elastic modulus is calculated by analyzing the change of sound velocity at different ages,and the cavity defect in concrete is judged and identified.It is proved that the FUT510 ultrasonic flaw detector has a strong application in the identification of concrete cavities.
