| Abstract: | Erhao-Dongsheng Highway Bridge of Inner Monglia is a 40 m multi-span highway bridge,which has the structure of simply-supported continuous prestressed T beams.In the process of prefabricating T beams,some cracks occur in a few T beams.The crack causes are analyzed from several aspects,such as mixture ratio,temperature and support sedimentation,and the corresponding counter-measures are put forward. |

| Keywords: | T beam crack mixture ratio temperature |
