Analysis of Porous Media Sediments on Seismic Response of Concrete Dams
Advanced Materials Research, 2020Co-Authors: Zhi Min SuAbstract:To solve the problem of sediments on Seismic Response of concrete dams, pressure wave formula of saturated porous fluid-solid two-phase medium was derived from the Bait’s consolidation theory, and was determined the Seismic Response magnitude of sediment on concrete dam. The method was applied to analyze the influence of sediments thickness and permeability on hydrodynamic pressures. Finally, a typical example is analyzed. The result shows sediments are able to decrease hydrodynamic pressures.

Transverse Seismic Response of beam aqueduct considering fluid-structure coupling
Acta Seismologica Sinica, 2007Co-Authors: Ri-chen Ji, Yao-long Chen, Li WangAbstract:Based on the theory of Housner, the transverse Seismic Response of beam aqueduct considering fluid-structure coupling 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 inertia action. When aqueduct cross-section is selected, the influence of ratio of depth and width to pier Seismic Response should be considered in order to reduce Seismic action.

TRANSVERSE Seismic Response OFAQUEDUCTS WITH FLUID-STRUCTURE COUPLING
Engineering mechanics, 2020Co-Authors: Xu Jian-guoAbstract:Aqueduct is a kind of thin-walled bar structures. Based on the theory of Volasov and Housner, a Seismic Response analysis model of thin-walled space aqueduct with fluid-structure coupling is established in this paper. In this model, transverse deformation, vertical deformation, longitudinal deformation, free torsion deformation, constrained torsion deformation and fluid-structure coupling between aqueduct and water body are all taken into consideration. The element stiffness matrix and the mass matrix of the thin-walled beam portion of aqueduct are derived by energy principle and the transverse Seismic Response equations are established without water or with design level water in aqueduct, respectively. Using the model, the Seismic time-history Responses of a single-pier aqueduct are calculated, and the model is verified through the comparison with analytical solution. Moreover, it is found that the Seismic Responses are different in the two cases of no water and design level water. The model is shown to be simple and practical for aqueduct's Seismic Response analysis with fluid-structure coupling.

Research on influence of water shake acting on aqueduct transverse Seismic Response
Journal of Hydroelectric Engineering, 2020Co-Authors: Ji Richen, Xia XiushenAbstract:The transverse Seismic Response of beam aqueduct with considering fluid-structure coupling is established in this paper.With the variety of aqueduct body disposal,the aqueduct transverse Seismic Response of a large-scale aqueduct under several work conditions is computed.The results show that the transverse Seismic Response is greatly influenced by the water mass in the aqueduct,but the shake water reduces itself Seismic Response.If the whole water is appended to aqueduct body,it will magnify the Seismic inertia action.When the aqueduct cross-section is selected,the influence of Seismic Response of aqueduct body on pier should be considered in order to reduce Seismic damage.
