摘　　要：高强预应力管桩作为一种新桩型以其施工方便、承载力高、质量可靠、较为经济等优点越来越得到广泛的应用。本文以海南某挡土墙工程为例,分析了高强预应力管桩作为基础桩应用于挡土墙时的水平承载力、竖向承载力及抗剪强度,得出此类管桩的承载力主要由其水平承载力控制,为科学合理的在挡土墙工程中应用高强预应力管桩提供参考。High strength prestressed tube-pipe becomes more and more widely applied because of its easy construction,high anti-pressure,good quality and economy.This article take a retaining wall of Hainan as an example to prove that the carry capacity of High strength prestressed tube-pipe is determined by horizontal level through analysis its horizontal carry capacity,vertical carry capacity and anti-shear intensity as the foundation pile of retaining walls,and take reference to scientific application in retaining walls engineering.
