| Abstract: | The article introduces the contents of static load test and detection methods of the bridges that the bridges are large-span variable cross-section continuous rigid frame box beam bridges. It made a comprehensive assessment on the mechanical properties and the distortion performance indices by comparative analysis of the theoretical calculation and the experimental results of the variable cross-section continuous rigid frame box beam bridges. This assessment provided some reliable technical information for the conservation and service of the bridges after operation. |
