| Abstract: | The destruction of bridge pavement layer can greatly shorten the life of bridge. Given this, based on the analysis of the mechanism of vehicle jumping at bridge head, the paper makes an theoretical analysis on traffic load and settlement at transition section of road and bridge, focuses on the prevention method of vehicle jumping at bridge head. The strengthening mechanism of geogrid is analyzed. Using the ANSYS finite element method （fern）, the bridge constitutive relation mathematical model is established, and by using numerical software, it calculates the efficiency of different solution method. |
