摘　　要：绿洲中环中心工程基坑面积呈圆形,直径大、面积大,采用直径200m钢筋混凝土圆环桁架支撑系统作支护体系,介绍支撑系统的造型、布置形式及内力的计算模式,并进行了实测值与计算值的对比分析。The foundation pit of Luezhou Zhonghuan main part has such characteristics as rounded area, large diameter, large area, reinforcement loop truss with diameter 200m used for support system. In this article, authors introduce something about the support system, such as the selection of form, layout, and calculation mode of internal force. At the last part, authors make a comparison between the monitoring results and calculational results.
