摘要:
通过对高桩码头震害的分析，阐明了高桩码头破坏的主要原因。在此基础上，从高桩码头抗震设计方法、桩 土相互作用、斜桩和桩-上部结构连接的抗震性能等方面，论述了国内外高桩码头抗震研究的进展，总结了这些研究成果在高桩码头抗震设计规范中的应用，指出了高桩码头抗震性能研究的不足及需要深入研究的问题。对国内如何吸收国外高桩码头抗震的研究成果及抗震设计规范的修订方向提出了建议。该系列论文分为3部分，此为第1部分，主要介绍了高桩码头的震害和破坏形式以及高桩码头的抗震设计方法。分析表明，基于位移的设计方法是国外高桩码头抗震设计的主要发展方向，我国应开展相关研究，将基于力的抗震设计规范修订为基于位移的抗震设计规范。

Abstract:
The main damage reasons resulting in poor seismic performance of the high-pile-supported wharves are clarified by examining extensive documented case histories of the damaged pile-supported wharves. The state of the art of the research on the pile-supported wharves, from the aspects of the seismic design methods, soil-pile interaction, seismic performance of the batter piles and the pile-deck connections, is presented, and the application of the findings from the seismic design codes for the pile-supported wharves is summarized, and the deficiencies in the studies and the problems need to be further studied are pointed out in this paper. Some suggestions are made as to how to absorb foreign research results about the seismic research on the high-pile-supported wharves and revise the seismic design codes for the pile-supported wharves. This paper is the first part of a series of papers, which mainly presents the earthquake damage, failure behavior of the pile-supported wharves and seismic design methods for the pile-supported wharves. Research results show that the design method based on displacement is the main development direction of the seismic design for the pile-supported wharves abroad, therefore, our country should carry out related seismic researches and revise the seismic design codes for the pile-supported wharves from that based on the force to that based on the displacement.
Key words:  pile-supported wharves  earthquake disasters  failure modes  seismic design methods
