智能化桩基超声波CT检测系统研究

提出智能化桩基超声波CT检测系统是超声波检测技术发展的方向。它主要通过跨孔扇形检测得到数据，CT智能反演成像得到图像，分析得到缺陷情况。这里系统地介绍了智能化桩基超声波CT检测系统的形成、理论基础、关键技术和应用情况, 引入了模拟退火反演的理论，分析了两者的相互关系。经工程实例验证，超声成像技术能较好地反映桩体内部缺陷情况，包括大小、严重程度，且结果直观。

Study of intelligent pile ultrasonic CT testing system

The intelligent pile ultrasonic computerized tomography (CT) testing system represents a direction of development for ultrasonic testing technology. Its main characteristic is data got by cross-hole fanning testing, and ultrasonography got by CT inversion. The formation, basic theory, key technique and application of the intelligent pile ultrasonic CT testing system are discussed systematically. The simulated annealing algorithm(SA) is used; and the relationship between CT testing system and SA is analyzed. According to project cases, the data of defective like scale、severity, will be got by ultrasonography. In addition, the result will be gain visually.
