철도 노반분니 현상에 대한 연구

초록

The status of mud-pumping in the conventional railroad lines were investigated and real-scale tests simulating mud-pumping phenomena were carried out to analyze its mechanism. The penetration of ballast material into the subgrade and the cause of mud-pumping are explored. The results of the investigation and tests will be used to develop the new method and materials for the prevention of mud-pumping.
