| 摘 要： | 针对夯实水泥土桩的施工方法，在桩身埋设特制的应变传感器，测定桩身应变，进而计算桩身轴力，由此得出桩侧摩阻力，在此基础上分析夯实水泥土桩荷载传递规律及侧摩阻力的分布特征。结果表明，由于夯实水泥土桩体强度的限制，荷载沿桩身的传递限定在浅层一定范围内，桩身变形、轴向荷载、桩侧摩阻力分布主要发生在此范围内，而且变化梯度较大。

| Abstract: | Aiming at special method of installation of rammed soil-cement piles, a new type of strain transducer in pile was proposed. And then, based on loading test data of rammed soil-cement single piles, load transfer behavior of rammed soil-cement piles and distribution of shaft resistance in single pile are studied. Results show that transmission of loads along pile are limited to a certain range at the shallow depth due to limited strength of rammed soil-cement pile. The deformation, axial load, distribution of shaft resistance occurred mainly within this range; and the varying gradient of every variable is larger. |

| Keywords: | rammed soil-cement pile axial load distribution of shaft resistance load transfer behavior |
