The settlement of railway subgrade has an important connection with the quality, safety and natural life of the railway, the excessive settlement of subgrade will directly cause too many problems in the process of railway using. Especially in high speed railway, these problems will be more outstanding, thus affecting the development and progress of the railway. For the foundation of traffic infrastructure in areas with soft subsoil often embankments supported by piles are necessary due to the settlement requirements. For sufficient load transfer into the piles different construction methods are possible. For the construction of a high speed railway, a cement stabilization of the embankment material and geogrid reinforcement on top of the piles were used. Before the temporary load the settlement is monitored continuously for 10 months. In this paper, the method of construction is described and important field monitoring results are presented.
