| Abstract: | The long spans pre-stressed concrete beam bridges have been built in highway project, the paper analysed the damages of the beam cracks and mid-span down deflection in terms of the overall structure design ,pre-stressed construction and structural calculation. The structural design optimization was advised on improving the concrete structure durability. |
