摘要

结合实际工程运用山原法、Randolph法、murff法对扬州地区预应力管桩的土塞效应进行了分析计算,解释了管桩承载力较试桩提高的原因。建立了管径、管壁厚度、桩长与土塞效应相对关系,可为扬州地区预应力管桩设计施工提供参考。
According to actual projects,the forming process of soil plug of prestressed pipe piles is analyzed based on the theory of Shanyuan,Randolph and Murff.The increasement of carrying capacity of the pile is explained compared to the test results.The relationship of the pile diameter,the thickness of the pipe wall and the length of the pile with the soil plugging effect is proposed,which provides some references for the design and construction of PHC pipe pile in Yangzhou.
