【摘要】：通过对高桩码头震害的分析,分析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2部分,主要介绍高桩码头抗震计算中桩-土相互作用的评估方法以及高桩码头的动力分析方法和研究成果。研究表明,评估桩-土相互作用的方法已较为完善,而对高桩码头抗倒塌性能以及近断层地震动下码头反应特性的研究还有待深入。
[Abstract]:Through the analysis of the earthquake damage of the high pile wharf, the main causes of the damage of the high pile wharf are analyzed. On this basis, the advances in seismic research of high pile wharf at home and abroad are discussed 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. Some suggestions on how to absorb the research results of high pile wharf and the revised direction of seismic design code are put forward in this paper. This series of papers is divided into three parts, this is the second part. It mainly introduces the evaluation method of pile-soil interaction in seismic calculation of high pile wharf, the dynamic analysis method and research results of high pile wharf. The results show that the method of evaluating pile-soil interaction is quite perfect, but the research on the anti-collapse performance of high-pile wharf and the response characteristics of wharf under near-fault ground earthquake still needs to be further studied.
