Abstract

In this paper,geocells with height of 0.10,0.15 and 0.20 m are applied to treat the subgrade subsidence. The dynamic stress in subgrade soil and the replacement thickness for three kinds of geocells are studied.The higher is the results show that height of geocell,the quicker is the decay velocity of dynamic stress under rail and the thinner is replacement thickness.
