Abstract: For Banpo Bridge in Liang-wang Expressway，the mechanical behaviors of hollw pier under the high filled with soil are analyzed．The soil pressure on the pier is simplified as a trapezoid loads．The computed results indicate that the FEM modle Carl effectively describe the mechanical state of hollow peir．

Key words: hollow pier；high filling soil；trapezoid loads, 3D finite element analysis

摘要： 以重庆梁万路半坡大桥右线为例，对变截面空心桥墩在高填土作用下的受力行为进行了分析，通过指定荷载 梯度模拟填土压力，计算结果全面反映了钢筋硷变截面箱形墩的受力状况．
