| 摘 要： | 复合载体夯扩桩是由干硬性混凝土及填充料等经细长锤夯扩形成的复合载体和钢筋混凝土桩身组成，具有挤密地基和扩大桩端面积等的作用。分析了复合载体夯扩桩的作用机制，并结合工程实例，采用太沙基公式和规范推荐的理论公式计算了复合载体夯扩桩的极限承载力和沉降量，并与现场静载试验结果相比较。结果表明，理论计算结果比试验结果偏于保守，并提出了相应的改进方法。

| Abstract: | Ram-compaction piles with composite bearing base, which has the function of densifying the foundation and enlarging the end area, is composed of Ram-compaction Piles, steel concrete formed by the non-plastic-concrete, packing, etc.. The action mechanism of the Ram-compaction piles with composite bearing base was analyzed. Based on the practical case, the K. Terzaghi formula and theoretical formula are applied to calculate the capacity and settlement, the calculated results were compared with the testing results. The results show that the theory is more conservative than the testing. The improved method was presented. |
