Based on the main features of high embankment in mountainous area,finite element analysis is made on the elasto-plastic consolidation under complex conditions with the consideration of different land forms,different contact conditions,different outlet locations and drainage conditions of groundwater,and different filling speeds.

Based on the upper bound theory of limit equilibrium analysis,a formula is obtained for the plastic work rate that takes place in a frozen embankment consisting of a perfectly plastic material obeying the non-linear failure criterion with an associative flow rule in the plane strain regime.

In order to research the relation between the cooling effect and ballast layer height,the natural convection index for representing the cooling effect of natural convection of ballast embankment in cold regions was introduced based on the natural convection theory and the thermal conduction theory in porous media.
