| 摘 要： | 采用有限元方法对大型穿河渡槽进行了上、下部结构整体动力学分析，得到了槽内不同水量时结构的固有频率及在地震荷载作用下渡槽的动应力分析结果。计算表明：大型渡槽结构的动力学特性与其它结构相比具有其本身特有的性质，这些特性为进一步实施动力学控制提供了良好的借鉴

| Abstract: | Using FEM of 3-D, global dynamic analysis of large aqueduct bridge(LAB) has been performed with upper and lower structure,natural frequency and dynamic stress of LAB has been obtained with varying water and under earthquake load. The calculation results have demonstrated that the dynamic properties of LAB have speciality compared with other structures, and these properties provide well basis for practising dynamic control. |
