摘要
结合现场实际工况,基于有限元数值计算软件建立堆土坡道数值分析模型,分析堆土和桥梁结构之间的影响,并对箱梁翼缘板位置混凝土的局部受压进行验算。结果表明,采用堆土坡道会对承台墩身水平方向产生较小的影响,水平方向变形值均在规范要求范围内,箱梁翼缘板处局部受压满足承载力要求,为同类工程的应用提供参考依据。
Combined with the actual working conditions,based on the finite element numerical calculation software,a numerical analysis model of piled soil ramp is established to analyze the influence between piled soil and bridge structure,and the local compression of concrete at the flange plate of box girder is checked.The results show that the horizontal direction of pile cap pier is less affected by the use of soil-piling ramp,the horizontal deformation values are all within the code requirements,and the local compression at the flange plate of box girder meets the bearing capacity requirements,which provides a reference for the application of similar projects.
