摘要
广州花都新华祈福A区基坑西侧采用双排水泥搅拌桩(内置竖向钢花管)+预应力锚索+土钉的支护形式以控制基坑变形并达到止水效果,该支护形式为现行基坑支护规范所未提及,在工程中的成功应用对类似地质条件的基坑支护工程有一定的借鉴意义。
In the west part foundation pit of zone A of Guangzhou Qifu building, the system of double- row cement mixing pile with vertical steel floral tube embedded and pre-stressed anchors and soil nailing is adopted to control its deformation and cut off water. The system is not mentioned in the current code of foundation pit supporting. The application of the system in this project can be used as references for the other foundation pit supporting projects with similar geologic conditions.
