Being a new kind of subgrade structure, pile-board structure is normally applied in the high-speed railway to meet the strict deformation requirement when the trains run across the specific areas where cannot be built traditional sections of the structures restricted by terrain conditions such as deep soft soil, collapsible loess foundation, and short subgrade transition between bridge and tunnel, etc. In some cities, this structure is being used when tram threads the soft foundation. Different from high-speed railway design experience, the tram is light axle loaded with low speed, and has different forms on track structure. In this paper, a research approach called “divided” on pile-board structure is presented. After simplifying the model, a theoretical design method is employed which combines the stiffness in structural mechanics with the ground coefficient in foundation engineering. Furthermore, a 3D entity model by finite element software ANSYS is built. Such factors as physical properties of materials and geometrical sizes of the structure, which will influence static stress and deformation, are analyzed and optimized. Finally, the whole model will be set up and do further its dynamic response analysis to verify feasibly and a dimensional scheme will be put forward.
