锦屏3#营地液化地基振冲碎石桩加固处理技术

 在锦屏水电站3#营地基础加固中，应用振冲碎石桩法加固深厚粉细砂层地基，有效提高地基承载力，明显消除了地基土的可液化性，减少基础沉降量和不均匀沉降，满足修建多层建筑的设计要求。通过该工程实例简要介绍了振冲碎石桩加固地基的设计及施工方案、施工工艺、质量控制以及质量检测结果，实践表明采用振冲碎石桩加固可液化地基具有快速、方便、可靠的特点。

Vibro-replacement Stone Column Technique on Liquefied Foundation in No.3 Camp of Jingping Project

The vibro-replacement stone column technique was successfully applied to the foundation reinforcement in No.3 camp of Jinping Project.After using the technique,the bearing capacity of the foundation was improved,the foundation liquation was eliminated obviously,and the settlement quantity and un-uniformity settlement value were reduced.By an illustration,the purpose,the design and construction scheme,the construction technique,the quality control and quality detection of vibro-replacement stone column were ...
