For the land-connecting structure design of piled wharf in strong seismic zone，based on a practical engineering case and using qualitative and quantitative analysis method，we compare and analyze the performance of frequently used land-connecting structure such as concrete retaining wall installed on slope，cantilever sheet pile wall and anchored sheet pile wall，and propose a new land-connecting structure of anchoring settlement slab，the characteristics of which are expounded. The research shows that，compared with the traditional land-connecting structure，the anchoring settlement slab is an economic and convenient option in strong seismic zone，which has better adaptability to slope settlement and deformation and is more advantageous to guarantee wharf operation and quick damage-repair after earthquake.
