운영중인 철도노반 보강을 위한 약액의 침투성능

초록

This study deals with the infiltration performance of the chemical grouting in the ground reinforcement method to reinforce the railway roadbed that has subsided in an operating railway. On the ballasted track, the roadbed settlement can be corrected through the roadbed, but it is almost impossible to reinforce the roadbed in the concrete orbit. However, in order to secure the safety of the train, the only way to lift the rails without restoring the roadbed was through the orbit restoration method. These orbit restoration methods are temporary not work well because they are not reinforced on the roadbed. This problem occurs re-settlement due to improper use of materials of soft ground and roadbed. Moreover, there is no case in Korea that reinforces the roadbed to the railway that is in operation. Therefore, in order to reinforce the railway roadbed in this study, the existing method of the chemical grouting method, which is the ground reinforcement method, was examined and basic studies on the infiltration performance and conditions were conducted.
