Abstract
This paper presents the results of plate load test and dynamic load test performed to evaluate the performance of geocell which is used to reinforce soft subgrade for high-speed railroad. Efficiency of geocell was observed in the increase in bearing capacity of subgrade and in the reduction of thickness of reinforced sub-ballast. One layer of geocell underlying a 10 cm thick cover soil led to an increase in bearing capacity three to four times larger than that of a crushed stone layer of the same thickness substituted for the geocell and cover soil layer Given the test conditions, the thickness of reinforced sub-ballast can be reduced by approximately 35 cm with the presence of geocell.
