摘　　要：在富水软土地基工程中,选择合适的施工技术是确保工程稳定性和安全性的关键。SMW(Soil Mixing Wall)工法桩与预应力型钢组合支撑施工技术因其优越的止水性能和承载能力,成为解决此类地基问题的有效方案。详细探讨了该组合技术的应用,包括施工流程、设计参数、质量控制措施及应对挑战的策略。SMW工法桩通过将水泥浆与土体搅拌形成高强度连续墙体,提供优异的防渗性能和承载能力。预应力型钢支撑则通过施加预应力,增强支撑系统的刚度和抗变形能力。两者的结合有效提高了基坑支护系统的整体性能,确保施工的顺利进行和后期使用的安全性。In water-rich soft soil foundation engineering,selecting appropriate construction technology is crucial for ensuring project stability and safety.The SMW(Soil Mixing Wall)construction method piles combined with prestressed steel support technology offer superior water-sealing performance and load-bearing capacity,making them an effective solution for such foundation challenges.This paper explores the application of this combined technology,including construction processes,design parameters,quality control measures,and strategies for overcoming challenges.SMW piles mix cement slurry with soil to form a high-strength continuous wall,providing excellent impermeability and load-bearing capabilities.Prestressed steel supports enhance the stiffness and deformation resistance of the system.Together,they improve the overall performance of the foundation support system,ensuring smooth construction and long-term safety.
