Research on the dynamic characteristics of the high-piled wharf considering soil-structure interaction

Based on a practical engineering, the effects of soil structure interactions on the dynamic characteristics of the high piled wharf were investigated, and the influences of different soil structure constraint styles and initial earth stress on the calculation of dynamic parameters were also studied. The results of the study were the following: (a) the soil-structure interactions should be considered when analyzing the dynamic characteristics of the high-piled wharf; (b) the soil-structure constraint styles would influence the calculation of dynamic parameters, and soil structure constrained by contact elements was recommended; (c) the consideration of initial earth stress would increase the frequency of the high-piled wharf and had much greater influences on high order, so the soil initial earth stress should be considered when performing the modal analysis of soil-wharf.
