Abstract：Research purposes: For the further optimization and determination of the compaction standards for the subgrade structure，filling materials and all structure layers of high － speed railway，the transmission and distribution of the vertical stress of the high embankment in the standard subgrade bed with the different deep planes under the effects of the train loads on the single track，double tracks and four tracks were analyzed with finite element method，and the corresponding transmission and distribution laws were offered．
Research conclusions: The train load on the the subgrade top was down transmitted almost along the 45°direction． The load was overlapped in the bedding bottom under the effect of the train loads on the multiple tracks． The vertical stress in the foundation base caused by the train load was distributed unevenly and it was distributed with a curve that the stress in the middle region was bigger than that in the periphery． The maximum vertical stress appeared in the middle of the subgrade bed under the effect of the symmetrical train load．
