摘　　要：结合某狭长形状的深基坑支护工程实例,论述多圆环内支撑的布置原则和设计方法,并提出适用于支护结构设计的圆环内支撑刚度计算公式。对比分析基坑监测数据与计算结果,表明圆环内支撑对不规则形状的深基坑有较好的适应能力。With a foundation pit engineering example, layout principles and design method of mutiring bracing system in the foundation pit are discussed, while the stiffness formula is supposed for design of retaining and protection structure. The calculate results are compared with measured data. It is indicated that circular strut system has good adaptability in deep foundation pit with irregular shape.
