振冲碎石桩在内蒙沙漠化细砂地基土处理中的应用

Application of Vibroflotation Sand-gravel Pile on the Deserted Fine Sand Foundation Soil Treatment in Inner Mongolia

结合内蒙古伊泰集团16万t/a煤基合成油工程实例,对细砂土液化土层采用振冲碎石桩进行地基加固,该方法施工工期短,加固效果好,有效地提高地基承载力,消除液化,取得了良好的经济效果,并为合理开发和利用松散细砂土液化地基提供了有益的经验。

The paper combined Yitai Group to synthesize the oil engineering 160 kt/a coal illustration,vibroflotation sand-gravel pile was a doped on the foundation strengthening to the fine sand soil liquefaction soil layer. The construction period by the method is short, reinforce effect is fine, the foundation carrying capacity is enhanced, liquefaction is eliminated resulting in obtain good economic result. The beneficial experience is provided to the reasonable development and utilization of the loose fine sand soil liquefaction foundation.
