Development of a Non-Destructive Inspection System for Concrete Structures Using an Ultrasonic Sensor

根据超声波传感器波长与骨料尺寸大小的不同，提出了基于多次反射波模型和驻波模型的超声波传感器无损检测方法。此外，为了便于实际应用，还发展了具有划时代意义的电磁波雷达无损检测方法和排污泵系统超声波无损检测方法。综上所述，本文开发了一种由超声波传感器和电磁波雷达组成的有效无损检测系统，实现了对混凝土结构缺陷的检测。

Non-destructive inspection methods were developed using an ultrasonic sensor respectively based on a multi-reflected waves model and a stationary wave model, according to the difference of the magnitudes between the wave length of the ultrasonic sensor and the size of the aggregate. Also, the non-destructive inspection methods of the time domain were developed as well as those in the frequency domain, in order to ease their practical useAdding to it, an epoch-making non-destructive inspection method using an electromagnetic wave radar and an ultrasonic non-destructive inspection method of a sump pump system were developed in the extension of the ultrasonic inspection methods. To summarize them, an effective non-destructive inspection system composed of ultrasonic sensor and electromagnetic wave radar was developed to enable the detection of the defects in concrete structures
