摘　　要：预应力管桩在沿海地区应用越来越广泛,而桩侧摩阻力计算的经验公式不多,设计者往往凭借经验偏于保守地查表计取单桩承载力的侧摩阻力及端阻力,该文从影响桩侧摩阻力的因素着手,用土工参数,采用半理论公式计算对比的方法,计算某沿海地区预应力管桩桩侧摩阻力,对某沿海地区预应力管桩桩侧摩阻力的取值提供了较为准确的计算方法。Prestressed pipe piles are increasingly used in coastal area, but the formulas how to evaluate the pile side friction are few, designers are conservative to obtain pile side friction and point resistance force on single pile by looking up table. In this paper, to start by the factors influencing the pile side friction, by using geotecbnical parameter and contrast evaluation of semi theory formula, the prestressed pipe piles side friction is evaluated in a coastal area. It provides a more accurate method to evaluate prestressed pipe piles side friction, and provides basis to design prestressed pipe piles rationally.
