Abstract: The reinforced earth layer is very important to the performance of columngeogrid reinforcement in the embankment. The determination of the geogrid strength is the key to the proper reinforced earth layer design. The design approach of the columngeogrid reinforcement in a comprehensive test embankment section for the ballastless track for the SuiYu high speed rail is thoroughly discussed in this paper.

Key words: High-speed Rail, Ballastless Tracks, Column-geogrid Reinforcement, Reinforced Earth Layer
