云南鲁基厂水电站坝基振冲试验与施工

Vibroflotation Test and Construction of Dam Foundation of Lujichang Hydropower Station in Yunnan

摘要:

鲁基厂水电站坝基建在覆盖层地基上，地基为砂卵砾石层、块石层、泥质粉细砂等地层互层，天然地基承载力不能满足设计要求，采用180 kW大功率电动振冲器加钻机引孔的施工工艺，解决了地层复杂、振冲加固处理深度大的施工技术难题。

Abstract:

The dam foundation of Lujichang hydropower station was built on overburden formation with interlayer of sand gravel, block stone and shaly fine sand formation, the bearing capacity of natural foundation could not satisfy the design requirement; 180 kW high power electric vibroflotation device and drilling rig were applied to solve the construction difficulties in complex formation and deep vibroflotation consolidation.
