In order to evaluate the seismic performance of sheet pile wharves, including the displacement of quay walls and the stress states of structural members, the finite element method code PLAXIS is utilized in this study to establish the model of sheet pile wharves for dynamic seismic analysis. The nonlinearity of soil and structural members as well as the seismic response characteristics of layered ground are considered. Firstly, a scale-model shaking table test conducted by National Cheng Kung University and the Harbor and Marine Technology Center is simulated to verify the analysis method. Then, a sheet pile wharf in the Port of Hualien is adopted for a case study using the time history of a representative earthquake, and the obtained seismic performance is compared with its design conditions to confirm whether the design requirements are achieved. The results of this study can be applied to the seismic evaluation of sheet pile wharves, and can be used in the examination procedure in performance design. |
