摘　　要：针对在废黄河冲击平原,由于土层中有硬夹层,使得一般的全桩孔连续喷粉、复搅工艺难以顺利实施的问题,通过工程实例,介绍了分段喷灰,分段复搅的工艺,经施工验证,该工艺取得了较好的效果。Aiming at the problem that common whole.pile hole continuous dusting and mixing technologic could not smooth running due to soil layer of Huanghe impact plain had hard interlayer, combined with engineering examples, the segment dusting and segment mixing technology were introduced. The construction proved that the technology obtained better effect.
