Analysis on Overturning of Single Pier Bridge and Reinforcement Design Method
View through CrossRef
With the lesson from the overturning accident of single-pier bridge and based on the analysis on the size and distribution mode of the load on the bridge surface when the ramp bridge of Tianjin segment in the Jin-Jin Expressway collapsed, this Article drafts the load size and distribution mode are (possibly undertaking up to 4x165t load) studied out for analysis and design of single pier bridge of pier-girder consolidation for the analysis on the calculation of the overturning resistance for single-column girder, and analyzes the overturning resistance capacity of single-column girder with pier-girder consolidation according the planned load size and distribution mode. In addition, this Article proposes the reinforcement measures by adding the column supports at the horizontal direction of the single-column pier, thus effectively improving the overturning resistance capacity of main girder. This Article may be used as the reference for the study of overturning resistance and the reinforcement of single-column pier bridge.
