填土中的钢筋砼箱形变截面桥墩受力分析

Structure analysis of holloww peir in high filling soil

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砼变截面箱形墩的受力状况.

For Banpo Bridge in Hang-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 can effectivdy describe the mechanical state of hollow peir.
