| 针对国内水泥土搅拌桩应用中存在的质量问题，介绍了新研制的双向水泥土搅拌桩及其施工工艺；通过对双向水泥土搅拌桩与常规水泥土搅拌桩在现场施工工艺、标准贯入试验、桩体芯样无侧限抗压强度及软土地基加固效果分析等方面的对比研究，说明了双向水泥土搅拌桩优越的工程特性及应用前景。 |
| 英文摘要: |
| With the review of disadvantages of traditional deep mixing techniques in our country,a new bi-directional deep mixing technique and its construction techniques were introduced in this paper;By comparing present construction techniques,standard penetration test and unconfined compression test of deep mixing column,improvement effect of soft ground improvements and so on between the bi-directional deep mixing technique and traditional deep mixing technique. It is proved that the bi-directional deep mixing te... |
