Through field measurement for the contact pressure of box foundation with Ⅰ shaped plane of a high rise building on cobble subsoil, the distribution law of the contact pressure has been diagrammed. At the same time, the contact pressure has been calculated with finite compression layer model, which is well accordant with the measured result. The relative error of average value for the measured to the calculated contact pressure is 6.9%. This shows that the numerical calculation is right.

The computation model of two-point contact (for cone-tread) and conformal contact (for worn-tread) resulting from wheel flange close to rail is firstly established in this paper. A detailed analysis is made of the wheel/rail contact force, contact status and wheel/rail stress distribution on the different action of tractive forces and transverse forces. We draw some important conclusions, one of which is that the locomotive adhesion performance will decrease with the increase of transverse forces between wheel and rail.
