摘要
介绍了预应力管桩在竖向荷载作用下和水平荷载下的工作机理,并对预应力管桩土塞效应的产生和工作机理进行了分析,对预应力管桩的挤土效应及对侧阻力的影响进行了研究。结果表明:预应力管桩土塞效应与挤土效应是相互关联,互相影响的。
This paper introduces the working mechanism of prestressed pipe pile under vertical load and horizontal load,analyzes the generation and working mechanism of soil plug effect of prestressed pipe pile,and studies the soil squeezing effect of prestressed pipe pile and the influence of soil squeezing effect on lateral resistance.The results show that the soil plug effect and squeezing effect of prestressed pipe pile are closely related and affect each other.
