Abstract

Railway subgrade mud pumping is one of the most common defects. Unfavorable combination of soil, water, dynamic load is the main cause of subgrade mud pumping. Based on the source of water causing railway subgrade mud pumping, it can be divided into 5 major categories; on the basis of three stages forming mud pumping, the defect mechanisms are explored and the influencing factors are analyzed; identifying the defect categories is the premise of determining railway subgrade rehabilitation schemes, while geological radar detection is proved to be an effective mean appropriate for railway mud pumping detection; common mud pumping prevention measures are concluded, so as to provide references for the railway subgrade mud pumping defect controlling project.
