Analysis of Dynamic Characteristics of Pile-Soil-Water Coupling Effect in Consideration of Large Span Cable-Stayed Bridge

Abstract:

The effect of equivalent fluid and viscoelastic boundary form considering soil's effect on long span cable-stayed bridge dynamic characteristics are analyzed to consider the additional mass method. Through the analysis, some useful conclusions of considering the water after the dynamic characteristics of the structure change greatly, and with the increase of water depth, frequency gradually more and more small, decreased significantly are obtained. Considering the fluid, structure is not the same under static load internal force changes. The cable has little effect, but beam and tower impact significantly, such as the moment of the direction of Z increased by 272%, so, the action of the fluid must be considered.
