基于超声波的连续箱梁腹板混凝土密实情况检测

Detection of Concrete Dense Situation of Continuous Box Girder Web Based on Ultrasonic Wave

混凝土结构如果存在不密实或空洞等缺陷,会严重影响结构的承载力和耐久性。基于超声波的基本原理,采用超声波对混凝土缺陷进行检测分析,结合工程实例论述了超声波的检测过程。结果表明,超声波检测技术能够有效地反应混凝土中的不密实区和空洞部位。

The imperfection of concrete structure, such as not dense and cavity, would seriously affect the bearing capacity and durability of the structure. Based on the basic principle of ultrasonic wave, concrete defects are detected and analyzed by ultrasonic wave. Combing with practical engineering, test process of ultrasonic wave are discussed. The result shows that the ultrasonic wave can effectively react not dense area and empty part of the concrete.
