	<span style=\"line-height:1.5;\">本文在分析典型工程超长钻孔灌注桩试桩成果基础上，总结超长钻孔灌注桩桩侧摩阻力的发挥特征，并提出桩侧摩阻力的发挥取决于桩侧土体的抗剪强度指标(c, φ)、有效上覆压力及桩土间相对位移四个主要因素，其中桩侧土体的有效上覆压力及桩土间相对位移是影响超长桩桩侧摩阻力发挥不可忽视的因素。&lt;br/&gt;Based on the analysis on the results of test piles of typical projects, characteristics of pile shaft friction resistance are summarized for ultra-long bored piles. Pile shaft friction resistance mainly depends on shear strength index (c, φ), effective overlying pressure, and pile-soil relative move-ment. Effective overlying pressure and pile-soil relative movement are should not be neglected to pile shaft friction resistance.</span><span style=\"line-height:1.5;\"></span>
