【摘要】：通过对高桩码头震害的分析,弄清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,介绍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,并就如何吸收国外高桩码头抗震的研究成果及修订抗震设计规范提出了建议。本文为系列论文第3部分,主要论述了斜桩和桩-上部结构连接的抗震性能。研究表明,斜桩的抗震性能存在较大争议,国外在桩-上部结构连接形式及隔震技术方面进行了大量理论和试验研究并在码头抗震设计中得到应用,我国在斜桩使用和桩-上部结构连接等方面还需要继续深入研究。
[Abstract]:Through the analysis of earthquake damage of high pile wharf, the main causes of damage of high pile wharf are clarified. On this basis, the advances in seismic research of high pile wharf at home and abroad are introduced from the aspects of seismic design method of high pile wharf, pile-soil interaction, seismic behavior of inclined pile and pile-superstructure connection, etc. This paper summarizes the application of these research results in the seismic design code of high pile wharf, and points out the deficiency of seismic performance research of high pile wharf and the problems that need further study. Suggestions on how to absorb the research results of high pile wharf and revise the seismic design code are put forward. This paper is the third part of a series of papers, mainly discusses the seismic behavior of inclined pile and pile-superstructure connection. The results show that the seismic behavior of inclined piles is controversial. A large number of theoretical and experimental studies on pile-superstructure connection and isolation technology have been carried out abroad and applied in the seismic design of wharves. In China, the use of inclined piles and pile-superstructure connections need to be further studied.
