Abstract: The Finite Element Analysis program software is one of the widely used in the bridge engineering. Through using and understanding the software, the writer uses it to prove the stress state when the bridge deck overlay imperfectly contacts with the bridge deck and prove the impact of the ratio of the bridge deck overlay material elasticity module to the bridge deck elasticity module on the bridge deck overlay stress

Key words: finite element analysis, the bridge deck overlay, imperfect contact, ratio of elasticity module
