墩身刚度对小半径弯箱梁的受力影响

摘要

结合工程实例，为分析墩高对结构受力的影响，建立了不同的墩高模型，通过对多个模型的计算结果对比分析，研究了墩身刚度对小半径弯桥箱梁的受力影响，为城市立交匝道的设计提供了计算依据。%Combining with the engineering example,this paper analyzed the influence of pier height to structure stress,established the different pier height model,through the comparison and analysis on calculation results of multiple models,researched the force influence of pier stiffness to small radius curved box girder,provided calculation basis for city interchange ramp design.
