| 摘 要： | 弹性基础连续梁或铰接梁是进行浮桥结构计算时通常采用的力学模型。目前对弹性基础连续梁或铰接梁的计算大多还只按静载作用来考虑。从动力学微分方程出发，研究了匀速移动载荷作用下弹性基础连续梁和弹性基础铰接梁的计算方法。

| Abstract: | The continuous and hinged elastic base beams are the common used mechanic models in the structural calculation of floating bridges. At present, only the immovable loads are mainly considered in the calculating methods of the continuous and hinged elastic base beams. Based on the dynamic differential equation, the calculating methods of the continuous and hinged elastic base beams under the action of moving loads with uniform speed are studied in the paper. |

| Keywords: | elastic base beam moving loads dynamic response floating bridge |
