Abstract The heat influence law for structure in Qinghai—Tibet engineering corridor is significant to the new path selection of structure and keeping old structure stable. On the basis of same temperature boundary condition，taken height and width of embankment as impact factor，control equation which involved phase change and finite element method was applied，and heat influence law along the Qinghai—Tibet engineering corridor were studied. Results indicate that heat influence limit of embankment is highly sensitive to height and width of embankment. Width is positively correlated with heat influence limits while height is negatively correlated with. After 50 years，with the same height of 1.5 m，heat influence limit of 8 m wide embankment is 5 m smaller than that with 21.5 m wide embankment；with the same 21.5 m width，heat influence limit of 1.5 m high embankment is 2.3 m bigger than that with 5 m high embankment. And heat influence limits is obviously affected by north and south slopes effect：heat influence limits at south side is distinctly bigger than that at north side at the same time. Insulation board can weaken heat influence limits to some extent，but the effect is limited.

Key words： soil mechanics；Qinghai&mdash Tibet engineering corridor；roadbed in permafrost region；heat analysis；size effect
