Abstract:
Ground penetrating radar is the main method for detecting the disease of railway subgrade. It is difficult to establish a GPR image sample set, and it is difficult to carry out image recognition based on supervised learning. This paper proposes an intelligent identification method of railway subgrade diseases based on unsupervised learning, and uses k-means clustering algorithm and LandTrendr algorithm to realize automatic classification of railway subgrade GPR signals. The test results show that this method can distinguish three types of signals: normal, muddy and water-containing, and the classification accuracy rate reaches more than 95%.
