| 摘 要： | Based on the theory of Housner, the transverse seismic response of beam aqueduct considering fluid-structure cou-pling is established. With the variation of aqueduct cross-section ratio of depth to width, the aqueduct transverse seismic response change. The transverse seismic response of a large-scale aqueduct in several work condition are calculated. It shows that the transverse seismic response is greatly influenced by the water mass in the aqueduct, but the shaking water play a TLD role. If the whole water is appended aqueduct body, it will magnify seismic iner-tia action. When aqueduct cross-section is selected, the influence of ratio of depth and width to pier seismic re-sponse should be considered in order to reduce seismic action.

| Abstract: | Based on the theory of Housner, the transverse seismic response of beam aqueduct considering fluid-structure cou- pling is established. With the variation of aqueduct cross-section ratio of depth to width, the aqueduct transverse seismic response change. The transverse seismic response of a large-scale aqueduct in several work condition are calculated. It shows that the transverse seismic response is greatly influenced by the water mass in the aqueduct, but the shaking water play a TLD role. If the whole water is appended aqueduct body, it will magnify seismic iner- tia action. When aqueduct cross-section is selected, the influence of ratio of depth and width to pier seismic re- sponse should be considered in order to reduce seismic action. |
