| 摘 要： | 对不同墩高下的不对称高墩连续刚构桥成桥阶段进行了力学特性研究，获得了高墩连续刚构桥在不同墩高下的主梁和桥墩的内力、位移变形特性.研究结果表明，桥墩墩高的变化对主梁内力、主梁竖向位移、墩内力、墩横向位移均产生不同程度的影响，其中对跨中主梁竖向位移和墩顶剪力的影响较大，主梁竖向位移随着墩高的增大而增大，最大位移处平均增幅14.3%,墩顶主梁剪力随着墩高的增大而减小，平均变化率37.1%.

| Abstract: | The mechanical characteristics of asymmetric high pier continuous rigid frame bridges with different pier heights were studied to obtain the internal force and displacement deformation characteristics of the main girders and piers of high pier continuous rigid frame bridges with different pier heights.The vertical displacement of the main girder increases with the increase of pier height,with an average increase of 14.3% at the maximum displacement,and the shear force of the main girder at the top of the pier decreases with the increase of pier height,with an average change of rate of 37.1%. |
