摘 要: 从超声波场的理论计算公式出发,以混凝土介质为主要研究对象,将计算机层析成像技术用于混凝土质量的超声波检测,使得图像可直观准确地显示出混凝土内部的缺陷及损伤状况,并将理论计算结果与实际混凝土模型观测数据等相结合,深入研究超声波场在混凝土中的分布特征及振幅衰减特性,进一步研究适用于混凝土超声波衰减层析成像的成像算法,目前的研究目标是作为混凝土超声波衰减层析成像的基础研究。 Starting from the theoretical calctdation formula of ultrasonic field,considering concrete to be the main research object,the computerized tomography ultrasonic technique which can show the interior defects and damage situation with pictures intuitively and accurately is used to test the quality of concrete. Combining the theoretical calculation results with the observation data of actual concrete model ,after the distribution characteristic and amplitude decay property of ultrasonic field in concrete are investigated deeply,the algorithm suitable for computerized tomography of ultrasonic attenuation for concrete is further researched. The current target is to do the fundamental researches of computerized tomography of ultrasonic attenuation for concrete.
