| Abstract: | The universal finite element software of ANSYS was utilized in the mechanical analysis of pavement system on bridge deck. Firstly, the enveloping surface of the interface stress on bridge deck pavement was determined by means of moving loads. Then loads were arranged across the maximum stress influence surface of all the layers according to the criterion. Finally, the variation laws on several types of maximum stress in bridge deck pavement under concentrated load were explored, and thus the corresponding critical loading positions were determined. |
| Keywords: | tied-arch bridge asphalt pavement on bridge deck finite element critical loading position |
