深层搅拌桩与预应力锚杆复合施工技术应用

Application of Composite Construction Technology of Deep Mixing Pile and Prestressed Anchor Bolt

摘要: 本文基于实际工程项目探讨了深层搅拌桩与预应力锚杆复合施工技术的应用，根据基坑场地受限、位移及沉降控制要求高的特点，阐述具体的施工工艺技术及其质量控制措施。该技术通过深层搅拌桩与土体混合形成高强度复合桩体，结合预应力锚杆将拉力传递至稳定地层，有效分担了支护结构的荷载。不仅控制了基坑变形，还通过围梁连接形成协同受力机制，确保了周边建筑物及管线的安全，并取得良好的经济效益和社会效益，且可为类似工程提供参考。

Abstract: Based on the actual engineering project, this paper discusses the application of the composite construction technology of deep mixing pile and prestressed anchor, and expounds the specific construction technology and quality control measures according to the characteristics of the foundation pit site is limited, and the displacement and settlement control requirements are high. This technology mixes the deep mixing pile with the soil to form a high-strength composite pile, and combines the prestressed bolt to transmit the tensile force to the stable formation, effectively sharing the load of the supporting structure. It not only controls the deformation of the foundation pit, but also forms a synergistic force mechanism through the connection of the surrounding beams, which ensures the safety of the surrounding buildings and pipelines, and achieves good economic and social benefits, and can provide a reference for similar projects.
