高桩码头桩基设计关键技术环节

在港口工程设计文件中普遍存在针对高桩码头桩基设计疏漏的技术环节,桩基设计的完整性和合理性有待进一步提升。为此,通过对桩基规范条文的解读和引申,总结桩基设计过程中关于持力层的选择、承载力计算、桩身强度复核、打入桩沉桩控制标准以及质量检测等关键性技术环节中应着重注意的事项,为从事桩基设计者改进设计理念、提升设计质量、形成更趋完善和合理的桩基设计成果提供指导性意见。

Key technical aspects in foundation design of piled wharf

There are many technical problems in the pile foundation design of the high-pile wharf in the design documents about port engineering,so it is necessary to further improve the integrality and rationality of the pile foundation design.This paper summarizes the matters needing attention in the key technical processes in the pile foundation design,such as selection of bearing layer,calculation of bearing capacity,check of pile shaft strength and pile driving control standard and quality test,by means of interpretation and extension of the provisions of pile foundation specifications,offering the directive opinions for pile foundation designers to improve the design concept,upgrade the design quality and generate better and more reasonable pile foundation design results.
