截面

To resolve the design difficulties caused by small cross-section, low height of the bridge structure, the key technique problem to the bridge structure should be carried on research and analysis, such as whole calculation model, considering foundation combined action , the reasonable rigidity match to the joint of the girder and pier ,inner force redistribution caused by the system conversion ,the forecast to long-term deformation after building , stress analysis and tectonic steel bar of the anchored serration block , the influence of foundation settlement and anti- earthquake measures . To acquire feasible and reasonable technique parameters and provide the full design basis, according to analytical results adjust and optimize the bridge structure design.
