水泥搅拌桩+锚杆组合支护技术的应用

Application of Combined Support Technology of Cement Mixing Pile and Anchor Rod

文中结合福州双龙新城工程施工场地较为狭窄、岩土水文条件较差等问题,探讨水泥搅拌桩和锚杆组合支护设计方案,详细阐述了水泥搅拌桩和锚杆支护的施工技术要点。实践证明,在狭窄场地和软土地质条件基坑工程中,采用水泥搅拌桩和锚杆支护方案技术效益显著,具有良好的应用推广价值。

Based on the narrow construction site and poor geotechnical and hydrological conditions of Shuanglong New City project in Fuzhou,the design scheme of cement mixing pile and anchor bolt combinde support was discussed,and the key technical points of cemen mt ixing pile and anchor bolt construction were expounded in detail.Practice has proved that the use of cement mixing pile and anchor support scheme has good technical benefits and has good application and populraization value in the foundation pit engineering with narrow stie and soft soil condition.
