地质雷达在铁路路基挡墙质量检测中的应用

Application of GPR in Inspecting the Quality of Railway Subgrade Retaining Wall

地质雷达技术是一项高精度、连续无损、经济快速、图像直观的高科技检测技术。介绍了地质雷达技术及其在铁路路基挡墙质量检测中的应用。探测结果表明:与传统方法相比,地质雷达法具有明显优势,值得在工程检测方面推广和应用。

The technique of ground penetrating radar （GPR） is a high technology of examination, which has a lot of advantages such as high degree of accuracy, non-stop operation, non-destructive, rapid survey, audio and visual intuitions, etc. This paper presents the technique of GPR, and the application of GPR in the quality examination of subgrade retaining wall of railroads. The result of the application indicates that the technique of GPR is better than the traditional one. It is worthwhile to promote and apply the technique of GPR in the engineering examination.
