水下打桩导向架结构设计分析方法

摘要

打入桩是海洋工程中系泊系统常用的一种基础形式,桩在自由站立情况下的稳定性是进行打桩作业的前提.当在自重作用下桩的入泥深度下无法保持其稳定性时,则需要使用打桩导向架对桩进行导向和扶正.本文结合位于深水区域打入桩基础工程实例,介绍了打桩导向架的结构设计分析方法.%Driven pile is a common type of foundations for mooring system in ocean engineering,the stability of pile stick up is the prerequisite for pile driving. When the pile is unable to maintain its stability at the end of self-weight penetration,the pile guide frame is needed for guiding and uppending. According to an engineering practice of driven pile foundation in deep water,this paper introduces the structural design and analysis method for the pile guide frame.
