| Abstract: | This paper introduced the working principle of GPR and its application to loess sinkhole disease in existing railway subgrade. The detection shows that the deduction from abnormal waveform has high reliability and the hidden troubles are positioned correctly so that the specific position and distribution range of existing quality defects may be detected to guide the disease control in the late stage scientifically. |
