摘　　要：介绍了试验桩的设计、锚固系统的设计及荷载试验过程,实测了试桩的Q-s曲线s、-lgt曲线、轴力沿桩身的分布规律、桩侧摩阻力的分布规律,对大直径钻孔桩的竖向传力机理进行了分析。This article introduced the design of a test pile＇ s design and anchoring system, as well as load test process. It drew Q-s and s-lgt curve according to the measured data, which obtained the distribution about axial force along the pile and lateral friction of the pile. It also analyzed vertical-force mechanism of the large-diameter bored piles.

关 键 词：大直径钻孔桩 荷载试验 竖向传力机理
