| 摘 要： | 针对无伸缩缝桥梁的结构特点，提出一个土-结构的非线性相互作用模型。在此基础上对-无伸缩缝实桥建立有限元模型，分析了不同烈度地震作用下结构的动力特性，并与相应的有伸缩缝桥梁进行比较。文中还计算了主要结构参数对动力特性的影响。研究结果有助于对该类桥梁力学性能的认识。

| Abstract: | In this paper, a nonlinear soil-structure interaction model of jointless bridges is presented according to its structural characteristics. The finite element model of a jointless bridge under different earthquake intensities is built based on this. The dynamic properties are analysed and compared with that of joint bridges. The influence of chief structural parameters are also analysed. The research results are helpful for the knowledge of mechanics property of these bridges. |
