摘要
本文探究了超声波无损检测技术在水工建筑物混凝土结构缺陷检测中的应用.从输水渠道、泵站、闸门底板和管护道路跨支沟交通桥梁上选择 12 条裂缝,在裂缝附近布置检测区,测试超声波无损检测技术能否顺利测出混凝土结构缺陷.结果表明,在裂缝动态扩展的超声波检测中,随着施加力的增加,混凝土结构的裂缝深度加深,相应的声时值也会变高.由此可知,超声波无损检测技术可以较为准确地测出混凝土结构缺陷,为混凝土结构的维护提供了依据.
Abstract
This paper explores the application of ultrasonic non-destructive testing technology in the detection of concrete structural defects in hydraulic buildings,selects 12 cracks from the water supply channel,pump station,gate bottom plate,and pipe protection road cross-ditch traffic bridge,and sets up testing areas near the cracks,to test whether ultrasonic non-destructive testing technology can successfully detect concrete structural defects.The results indicate that in ultrasonic testing of dynamic crack propagation,as the applied force increases,the crack depth of the concrete structure deepens,and the corresponding sound time value also increases.From this,it can be concluded that ultrasonic non-destructive testing technology can accurately detect defects in concrete structures,providing a basis for the maintenance of concrete structures.
