探地雷达厚度曲线绘制技术研究

在隧道无损检测中,由于数据量大,绘制成果曲线图往往需要花费大量的时间和精力。针对这一问题,通过对探地雷达成果图中所含元素的研究,在Excel VBA开发平台的基础上设计并编制了专用的绘图宏。通过一键化执行该宏文件,可实现绘图中间过程的后台化,成果曲线绘图工作一键化、自动化,大幅降低了人为操作,从而在绘图过程中避免了误操作。与传统绘图方式相比,绘图效率大幅度提升,且雷达数据量越大,绘图效率越高。该绘图宏实现了层厚度曲线绘图工作的一键化、自动化、后台化、高效化,并避免了中间处理过程的误操作,具有较好的实用性和通用性。

Technical Research on Thickness Curve Drawing in Ground Penetrating Radar Testing

Due to the large amount of data in the tunnel nondestructive testing,it often costs a lot of time and energy to draw the curve graph of testing results. Aiming at this problem,the paper designs and compiles a specialized drawing macro based on the development platform of Excel VBA and the elements studies contained in the Ground Penetrating Radar( GPR) curve graph of results. Through the execution of this macro file with only one key,the process of drawing graph could run in the background. The one-key and automatic operation in the curve graph of results greatly reduces the human operation and avoid misoperation in the drawing process. Compared with traditional drawing method,one-key execution greatly improves drawing efficiency with larger amount of data and higher efficiency. The drawing macro realizes one-key,automation,background processing and high efficiency of the layer thickness curve drawing,and avoids misoperation in the intermediate processing. It has excellent practicability and generality.
