摘　　要：基于埋设有测试元件的足尺钻孔灌注桩的现场静载荷试验 ,研究了软粘土地层中桩长 2 8m ,桩径 6 0 0mm钻孔灌注桩的承载力 -沉降性质 ,同时研究了试桩的荷载传递特性 ,分析了桩身轴力、桩侧阻力及桩端阻力的发挥规律 ,并就单桩的沉降变形进行了计算分析 ,得到了一些有益的结论。Reinforcement gauges are installed in main steel bars of the bored pile in soft clay. By means of static loading test, the character of loading-settlement is investigated. At the same time, the developing process of axial force, lateral friction and tip resistance are obtained, and settlement of the pile is analyzed and calculated based on the experimental data. So some beneficial conclusions are obtained.
