| 摘 要： | 首先分析了截面刚度与桥梁下部计算时需用到的墩台顶抗推刚度的区别,然后将墩台顶抗推刚度进行了简单推导,最后比较分析了单薄壁墩与双薄壁墩的抗推刚度,以期为类似桥梁设计提供指导。 |
| 关 键 词： | 桥梁 墩顶抗推刚度 位移 变形 |

| Abstract: | The paper analyzes the differences of the anti-pushing rigidities in the calculation of the section stiffness and the calculation of the lower parts of bridges,induces the anti-pushing rigidity of pier tops,and compares and analyzes the anti-pushing rigidity of the single thin-wall pier and the double thin-wall pier,so as to provide the direction for the similar bridge design. |
| Keywords: | bridge anti-pushing rigidity of pier top displacement deformation |
