摘要:

跨海或库区的大跨度桥梁在地震作用下不仅需要考虑水体与桥墩的动力相互作用,同时由于各桥墩间跨度较大应考虑地震输入的行波效应。该文采用辐射波浪理论求解桥墩地震动水压力,建立了考虑地震动输入空间效应的深水桥梁地震响应分析方法,并考虑行波效应对深水连续刚构桥进行地震响应分析。研究表明:动水压力增大了桥梁结构的地震响应,其影响程度随着输入地震波和墩梁约束条件的不同而有所差异;考虑行波效应时地震动水压力对桥梁结构动力响应的影响较一致激励而言有所差别,同时地震动水压力对桥梁地震响应的影响随着视波速的不同而变化。由此得出结论,为合理评价地震动水压力对深水长大桥梁动力响应的影响应考虑地震动输入的行波效应。

Abstract:

Water-bridge-pier dynamic interactions should be considered in the earthquake response analysis of bridges located in the sea or reservoir area, and the traveling wave effect also cannot be ignored for long-span bridge structures. The hydrodynamic pressure formulary of bridge piers is solved using radiation wave theory, and a seismic response analysis method of bridges in deep water is established, which can consider the spatial effect of a ground motion input. The earthquake response analysis about a continuous rigid-framed bridge is made, considering the traveling wave effect. The results indicate that: dynamic responses of a bridge in deep water is augmented because of hydrodynamic pressure action, and the influence of hydrodynamic pressure on seismic responses of a bridge in deep water is changed with different earthquake wave excitations and constraint conditions about a pier-box girder. The effect of hydrodynamic pressure on the earthquake response of a bridge in deep water is different, considering traveling waves relative to a uniform excitation, which is also changed with apparent wave velocity when the traveling wave effect is considered. In conclusion, the traveling wave effect should be considered in seismic response analyses of long and huge bridges in deep water under hydrodynamic pressure actions.

Key words: bridges in deep water , earthquake action , earthquake induced hydrodynamic pressure , radiation wave theory , traveling wave effect
