| 摘 要： | 对夯实水泥土楔形桩复合地基的平均沉降随荷栽的变化规律、平均桩一土应力比以及桩身荷载传递规律进行了试验研究。结果表明：在相同荷载作用下，有土工格栅复合地基与无土工格栅复合地基相比，平均沉降小，平均桩一土应力比大，桩身轴力大；在相同的荷载时，桩身轴力中桩最小，角桩最大。

| Abstract: | The law of the average settlement varying with load,the average pile-soil stress ratio and the load transfer law for the composite foundation with rammed cement-soil piles were studied experimentally.The results indicate that under the same load,the average settlement of composite foundation with geogrid is smaller than that of composite foundation without geogrid,the average pile-soil stress ratio with geogrid is larger than that without geogrid and the axial stress of pile with geogrid is greater than that without geogrid.With the same load,the axial force of the center piles is smallest and the axial force of the corner piles is biggest. |
