“…In that earthquake, given that land transportation had been almost completely paralyzed, the emergency relief for delivering supplies to disaster areas was performed by utilizing seismic strengthening wharves (including the wharves put into service after emergency reinforcement), which played an important role in the entire relief process [1] [2]. In addition, while the restoration and reconstruction of the disaster areas are still in progress, the harbor green space can be used as temporary residential districts and storage sites for emergency supplies, further demonstrating the importance of functional wharves [3]. With the developments of national trade and container throughput, large-scale and specialized functional terminals have been successfully implemented and used.…”

Playing an important role in local and national seaport activities, container wharves are susceptible to structural failure and damage during earthquake events. Therefore, factors that affect the seismic response of crane-wharf structures under different types of earthquake ground motions should be elucidated. In this paper, 3D finite element models were established to investigate the differences of natural vibration characteristics between the wharf and crane-wharf structures. The dynamic response of a typical pile-supported wharf structure and the interaction behavior of a crane and wharf structural system under seismic actions of near-field and far-field ground motions were studied by performing numerical simulation and time-history response analysis. Axial force-moment relation curves were adopted to analyze the elastic-plastic limit state of the wharf structure under different ground motions. Results showed that the consideration of the container crane increased the natural vibration period of the pile-supported wharf structure and affected the dynamic characteristics of the structure. Compared with the far-field earthquake ground motion, the nearfield earthquake exerted a more significant impact on the structural dynamic response that controlled the elastic-plastic limit state. With the presence of a crane, the moment and shear force of the pile-top decreased and the location of the extreme value moved down obviously. The findings demonstrated that considering the crane changed the failure mechanism of the wharf structure, and the eccentric effect of the crane may amplify the dynamic response as the peak ground acceleration increases. The results provide reference for the seismic design and the evaluation of the seismic response of container wharves.

More than two hundred cases of effective stress analyses with variation of seismic coefficients and liquefaction resistance were conducted. Among the parameters considered in this study, the most sensitive parameter affecting the wall displacement under a prescribed level of shaking is the SPT N-value of subsoil below and behind the wall. With the results of parametric calculations, a simple procedure and charts are proposed to evaluate the order-of-magnitude displacement of a quay wall. It demonstrated the capability to evaluate a wide range of displacements, ranging from the displacement in the order of onetenths of meters to those with one order higher.
