| 摘 要： | 沉管压浆成桩承载力机理分析得知,压浆桩主要通过挤密、胶结、压浆劈裂和渗透、扩径作用来提高单桩承载力.设计了压浆成桩机具系统,确定了合理的压浆成桩施工流程和二次压注浆工艺参数.经对比分析认为,沉管压浆成桩法不仅可以实现桩型的转换、降低桩长、减少工程成本,而且可以改善桩周的边界承载条件,提高单桩承载力. |

| Abstract: | Analysis and research of the pressure mud vibro mechanism show that the pressure mud vibro can improve the load-bearing capacity through crowding,gluing,splitting diameter expanding.According to the mechanism a new machine tool system is designed and the proper pressure mud piling chart and the second pressure mud parameter are established.Compared to the normal method the new one mot only realizes conversion of pile type,reduction the pile length and lowering the cost but also improve the peripheral condition and load-bearing capacity. |
| Keywords: | vibro pile pressure mud load-bearing capacity |
