摘要
该文介绍了采用车载探地雷达系统,对运营铁路路基病害进行快速普查,为铁路工务提供病害预防与整治依据,为铁路的安全运营提供基础支撑。探地雷达法作为无损检测的主要手段,特别是在铁路路基病害探测中取得了较好的效果,通常能探测出翻浆冒泥、含水异常、下沉、基床不密实、基床不平整等病害。车载探地雷达系统为普查运营铁路路基病害提供了可靠快捷的方法。
This paper introduces the use of vehicle borne ground penetrating radar system for rapid survey of subgrade diseases of operating railway, which provides the basis for disease prevention and treatment for railway public works and provides the basic support for the safe operation of railway. As the main means of non-destructive testing, the GPR method achieves good results, especially in the detection of railway subgrade diseases. It usually can detect the diseases such as mud boiling, abnormal water content, subsidence, non-dense subgrade bed and uneven subgrade bed. The vehicle borne ground penetrating radar system provides a more reliable and quick method for the general survey of railway subgrade diseases.
