| Abstract: | 40m-span pre-stressed concrete box girders with pre-tensioned and post-tensioned tendons are designed respectively in this paper,and analysis on stress,stiffness and other mechanical indices were carried out with planner analysis software.The results show that the application of pre-stressed concrete box girder with pre-tensioned tendons in highway bridges of larger span is feasible. |

| Keywords: | box girder pre-stressed concrete pre-tensioned post-tensioned |
