摘　　要：超大规模深基坑,受周边环境紧张等多种因素影响,一般采用水平对撑、角撑、水平斜撑、圆环形支撑等钢筋砼结构。因此,本文提出超大规模深基坑钢筋混凝土圆形内支撑结构设计研究。通过对深基坑支撑数据进行计算,以此提高深基坑支撑结构的稳定性,对支护结构进行要点研究,确保坑壁结构稳定,最后完成钢筋混凝土内支撑设计。计算结果表明,该研究方法计算结果较为准确,安全性高,经济行好。Ultra-large scale deep foundation pit,affected by many factors such as the tension of the surrounding environment,generally adopts horizontal brace,Angle brace,horizontal diagonal brace,circular support and other reinforced concrete structures.Therefore,this paper puts forward the research on the design of reinforced concrete circular inner support structure for super large scale deep foundation pit.By calculating the support data of deep foundation pit,the stability of the support structure of deep foundation pit is improved,the key points of the support structure are studied to ensure the stability of the pit wall structure,and finally the reinforced concrete internal support design is completed.The calculation results show that the method is accurate,safe and economical.
