摘　　要：水泥土搅拌桩与锚杆组合支护结构较好地发挥了水泥土搅拌桩良好的止水性能和锚杆抗拉强度高的优点,是一种造价低、技术先进、安全可靠的新型支护结构。文章详细地介绍了某基坑采用该支护方法的设计、施工和监测,并对基坑开挖过程进行了有限元分析。支护方案的成功实施较好地保护了周边环境,同时也为同类基坑工程的设计和施工提供了借鉴。The lateral earth support system comprising soil-cement columns and anchors, is a new kind of support system, which is a low cost, advanced, and reliable one. This support system takes advantage of soil-cement columns＇ effective water sealing performance and anchors＇ high tensile strength. This paper introduces the design, construction, and field monitoring of an excavation, in which this kind of support system is adopted. The finite dement method is used to analyze the excavation. The successful implementation of the supporting scheme has protected the surrounding facilities. It is also provides some useful reference for the design and construction of the same kind of excavation.
