无填料振冲法在砂基加固处理中的应用

Application of non-additional material filling vibroflotation in sand foundation improvement

结合安哥拉某堆场地基处理工程,介绍了无填料振冲法在砂基加固处理中的应用。水、分段振密和密实电流是振冲施工质量控制的关键。针对潮汐对工程施工的影响、长时间无法达到密实电流值、砂层表层难以振密等典型问题提出了处理建议,归纳出振冲施工口诀。

Combined with a yard foundation treatment works in Angola, this paper describes the application of non-addititional material filling vihroflotation on sand foundation. Water, subsection vibration and dense current are the key of vihro construction quality control. In view of the tidal influence on the construction, the dense current can not be reached for a long time, the sand surface is difficult to vibration and other typically issues, the treatment recommendation is put forward, and the vibro construction formulas is summarized.
