Abstract:
In order to study the seismic vulnerability of pile-supported wharf structure, taking a vertical pile-supported wharf as the research object and considering the influence of the site, seismic spectrum characteristics and the uncertainty of ground motion intensity, we establish a dynamic nonlinear numerical model of structure-foundation soil coupling of vertical pile-supported wharf by using the geotechnical finite element software of Midas GTS NX. Selecting the maximum strain of pile foundation in soil as the damage index, we obtain the seismic vulnerability curves and the corresponding damage state probability based on the the incremental dynamic analysis method. The analysis results show that when peak ground acceleration is less than 0.80g, the wharf structure is mainly in mild damage state or moderate damage state, otherwise the probability of serious damage basically exceeds 50% and the structure will lose operational capacity. Based on the vulnerability analysis of pile foundation damage in foundation soil, the influence of earthquake on the vertical pile-supported wharf is described from macroscopic and quantitative point of view, which can provide reference for seismic design and disaster prevention prediction of vertical pile-supported wharf.
