双轴搅拌桩重力坝在大面积基坑中的应用

Application of Dual-axis Mixing Pile Gravity Dam in Large-scale Foundation Pit

双轴搅拌桩工艺作为重力坝主要用于面积小、开挖深度浅的基坑。在万源城C街坊商品住宅项目中,基坑临河、临地铁、周边小区密布及开挖面积大,双轴搅拌桩重力坝得到成功地运用,取得了较好的效果。介绍了该工程双轴搅拌桩重力坝的设计验算及施工工艺。

As gravity dam, dual-axis mixing pile process is mainly used in the small-scale and shallow foundation pit. This paper presents an engineering case, in which the large-scale foundation pit is near river, subway and residential districts, but dual-axis mixing pile gravity dam has been successfully applied. The design checking calculation and construction process are introduced.
