| 摘 要： | 对渡槽内流速对其横、竖向结构动力响应的影响进行了仿真分析.结果表明:流速对渡槽位移以及弯矩动力响应的影响虽然随着槽内流速的增大而加大,但是在1.0-2.5 m/s的范围内,流速所产生的附加数值很小,影响也很有限,不会产生危害.

| Abstract: | The influences of fluid velocity on dynamic responses of aqueduct were studied. The results show that the influence level of fluid velocity on dynamic responses of aqueduct is very limited within the design velocity range of 1.0-2.5m/s. So, for the aqueduct structural analysis, the influence of longitudinal flow can be negligible. |
