被动桩与土体相互作用的研究及进展

被动桩是一类在工程实践中经常出现的结构形式。阐释了被动桩的概念、形成原理,回顾了国内外在被动桩领域的研究进展和现状,分析了研究当中还存在的不足和目前急需解决的问题。最后,以软土地区城市建设基坑开挖对坑内工程桩的影响为研究背景,依托具体工程项目的现场测试、理论分析,初步研究了软弱地层深挖基坑中工程桩与流动土体相互作用的这一类被动桩问题,提出了一些有意义的结论,希望对类似工程建设具有一定的指导意义。

Progress of Interaction Between Passive Piles and Soil

Passive piles are a class of very common structure style in civil engineering.The fundamentals of passive piles is presented,and the progress and research are reviewed both in China and around the world.The defects and urgent problems are focused on as well.Finally,as an engineering item,empirical data and theoretical results are compared,and the piles in deep foundation ditch of weak layer,is studied by the interaction with flowed soil.Some important conclusions which are meaningful in civil engineering are obtained.
