振冲碎石桩在潇河综合治理工程橡胶坝及泵房项目中的应用

Application of Vibro-replacement Stone Column in Xiaohe River Comprehensive Management Project Rubber Dam and Pumping Station Works

本文结合工程实例,对振冲碎石桩的作用和施工方法及技术要点进行了分析。振冲碎石桩适用于处理砂土、粉土、粉质黏土、素填土和杂填土等地基,能很好地消除级配不良砂的地基液化等问题,极大地提高地基承载力,同时碎石桩施工方便,工期短,具有明显的技术效益和经济效益。

Engineering examples are utilized in the paper for analyzing effect, construction method and technical keys of vibro-replacement stone column. Vibro-replacement stone column applies to handling foundations made of sand, silt, silty clay, plain fill, miscellaneous fill and other foundations. It can well eliminate foundation liquefaction problems of bad graded sand, thereby greatly improving the foundation bearing capacity. Meanwhile stone column is characterized by convenient construction, short construction period, significant technical and economic benefits.
