| Abstract: | Crack is the great quality problem of prestressed box girder. There are many complex causes generating cracks, mainly including force and non-force. In the construction of engineering, cracks of prestressed box girder will be controlled effectively as long as each factor which may induce cracks is analyzed attentively, and corresponding prevention measures are adopted in time. |
