“…In addition, compared with the bridge on land, the sea-crossing bridge is always in deep water. e complex environment of the sea-crossing bridge also means that the seismic response and design of the bridge are quite different from those of the conventional bridge [3]. However, most previous studies focused on the seismic response of bridges constructed on onshore sites [4,5]; a comprehensive study on the seismic response of sea-crossing continuous girder bridge is rarely reported in the literature.…”

Based on the Hong Kong-Zhuhai-Macao project, considering the fluid-structure interaction and soil-structure interaction, the seismic response of a sea-crossing continuous girder bridge is analyzed. Three-dimensional nonlinear numerical bridge model is developed, in which the hydrodynamic force is represented by added mass and pile-soil interaction is represented by p-y elements. Meanwhile, stratification of soil is considered in the free field analysis. Through the comparison of responses of the bridge cases, the effects of earthquake-induced hydrodynamic force and pile-soil interaction are studied. For the influence of hydrodynamic force, the results show that it is relatively slight as compared with pile-soil interaction; moreover pile foundation is more sensitive to it than other bridge components. The influence of pile-soil interaction is relatively significant. When both of the interactions are considered, the influence is not a simple superposition of acting alone, so it is recommended to consider both factors in dynamic analysis.
