Abstract
Based on the structural performance requirements of long-span beam bridges,taking a certain large bridge construction project as an example,this study deeply investigates the intelligent design scheme of prestressed concrete simply supported-to-continuous beam bridges.The analysis is carried out in terms of the box girder cross-section,prestressing steel strand layout,continuous joint,and bearing arrangement.The research results showed that the structural deflection of the beam bridge was less than span/600,the non-uniformity coefficient of section stress was less than 1.5,the shear safety factor of the wet joint area was greater than 1.5,and all the indicators met the design requirements,which proved that the design scheme of the beam bridge had good practicability.关键词
