摘　　要：近年来,SMW工法广泛应用于城市基础设施建设和建筑领域,尤其在基坑支护工程中取得了显著成果。然而,传统的大型三轴搅拌桩机械在一些施工空间狭小的场合不具备可行性。为解决这一问题,研究介绍了在某深基坑围护结构项目中采用双轴搅拌桩技术的创新应用。该技术通过嵌入H型钢,兼顾了强度、刚度和施工空间的局限性,成功替代了传统方案。In recent years,SMW construction method has been widely used in urban infrastructure construction and building fields,especially in foundation pit support engineering,achieving significant results.However,traditional large-scale three-axis mixing pile machinery is not feasible in some construction spaces with limited space.To solve this problem,this article introduces the innovative application of biaxial mixing pile technology in a deep foundation pit enclosure structure project.This technology,by embedding H-beams,balances the limitations of strength,stiffness,and construction space,successfully replacing traditional solutions.
