Rubble-mound breakwaters are generally subjected to strong seismic waves propagating even when seated on weak soil deposits, and they interact with seawater in most cases. The purpose of this article is to understand the dynamic response of a rubble-mound breakwater with seawater-breakwater-foundation interaction after a real earthquake shock. In this study, employing the arbitrary Lagrangian-Eulerian approach and dynamic finite element method, in which the seawater and the foundation of rubble-mound breakwater are considered, the dynamic responses of rubble-mound breakwater during earthquakes are simulated using the LS-DYNA finite element program. It is found that the seawaterbreakwater-foundation interaction does have a considerable effect on residual displacements of the rubble-mound breakwater. The influence on horizontal residual displacement caused by the effect of seawater-breakwater interaction is greater than that on the vertical residual displacement, and the seawater-breakwater-foundation interaction does not necessarily reduce the horizontal and vertical displacements but also increases them. The vertical component of earthquake has a considerable effect on hydrodynamic pressure on the breakwater face. This investigation considers the seismic behavior of rubble-mound breakwaters by taking into account the coupling between the hydrodynamic loading and the shaking of the structure. According to the results, presented in this study, it is significant to consider the effect of interaction for rubble-mound breakwaters seismic safety evaluation.

The dynamic numerical modeling theory and wave impact calculation method of gasbag type floating bridge (GTFB) were studied by using the multi-material Arbitrary Lagrangian-Eulerian (ALE) method and penalty function method. The air and seawater were described by the ALE method, the structure of floating bridge was described by the Lagrangian method and the coupling force between floating bridge and flow field was calculated by penalty function method. The floating bridge-fluid coupling models were established by HyperMesh software. Then, the models and calculation parameters were validated. The structural responses of the GTFB under solitary wave impacting were analyzed. The results show that the maximum contact force of hinge and maximum stress of gasbag appeared at the ends of the floating bridge, and the maximum bending moment of hinge appeared in the middle section.
