Abstract: Pile-slab structure is a new subgrade construction with the development of high-speed railways in China. It is currently used in a number of high-speed railways. However, it is mainly designed by the empirical design method since the interaction mechanism among piles, slab and subgrade soil is not clear. The supporting effect on the slab and the lateral constraint effect on piles caused by subgrade soil is not considered using the empirical design method. A three-dimensional finite element model including train, track and pile-slab structure is established so as to make a systemic mechanical analysis of the slab, piles and subgrade soil in pile-slab structure. The conclusions is as follows:(1) When the supporting effect on the slab is not considered, the stress of the slab increases by 11.8 % ~ 13.4 %, the stress at the bottom of piles increases by 10.3 % ~ 11.2 %, the deflection of the slab increases by 11.0 % ~ 12.0 %. (2) The vertical displacement of the slab increases by about 52.9 % that of piles increases by about 69.4 % after removing the soil of the embankment and the soft soil in the roadbed. This indicates that the embankment soil plays a significant role in the supporting effect on the slab and provides a positive frictional resistance on piles. (3)The lateral deformation of the pile-slab structure increases by approximately 25 % when slab and soil doesn't contact, indicating that the contact between slab and soil has a certain effect on the lateral deformation of the pile-slab structure. The lateral deformation of the pile-slab structure increases by about 2.5 times when removing the embankment layer, indicating that the lateral constraint effect on piles is very obvious. So the pile-slab structure has significant advantages compared with bridges.
