摘　　要：结合工程实例,对钢筋混凝土圆环内支撑支护技术应用于深基坑支护工程的设计与施工技术进行了详细论述,并对应用效果进行了分析。研究表明:圆环支撑受力体系合理,整体刚度大,保护周边环境效果好,土方挖运便捷。在软土深基坑中的成功实施表明,其具有较大的技术优势和经济价值,圆环内支撑是一种安全且较为经济的支护结构。Combining actual engineering, a design and construction technology of reinforced concrete ring bracing system used by deep excavation are mainly introduced in this paper, the application effect is analyzed. The results show that the force system of the ring support is reasonable, the overall stiffness is large, and the effect of protecting the surrounding environment is good. The earth is easy to dig and transport. The successful implementation in soft soil deep foundation pit shows that it has great technical advantages and economic value,and the inner ring support is a safe and economical supporting structure.
