摘要： SMW工法具有施工工期短、抗渗性好、对环境影响较小，工字钢可回收等优点，青岛红岛区存在部分上部为深厚海相软土，下部为坚硬岩石的典型地层，SMW工法在该地层中尚无应用先例。以红岛滨海土岩组合地层中某深基坑工程为例，探讨SMW工法桩在软土地层中的施工关键技术应用，主要针对施工中出现的问题进行分析并提出具体的应对措施，保证了工程的整体施工质量，总结了SMW工法桩在红岛滨海软土地区的施工关键技术，为滨海土岩组合地质条件深基坑工程的解决和临海城市的建设发展做出贡献，为类似工程提供借鉴参考。

Abstract: The Soil Mixing Wall (SMW) method has the advantages of short construction period, good waterproof, small impact on the surrounding environment and the hot rolled steel beams can be reused. It has been widely used in the deep excavation engineering where, the soft soil is widely distributed, such as Shanghai, Tianjin, Shenzhen and so on. The typical strata at Hongdao area shows that a thick layer of marine soft soil overlies the bedrock. The SMW method has not previously applied in this area. The investigation focuses on the key installation issues of the SMW application in the soft area based on deep excavation engineering in Hongdao coastal soil and rock composite stratum. The paper proposes the corresponding countermeasures to ensure the quality of the SMW column which can provide experience to similar projects and contribute to marine-rock strata deep excavation construction and development of coastal urbans.
