摘要
本文介绍了钢筋混凝土双环形支撑体系在海南三亚某基坑工程中的成功应用。根据本基坑周边环境的特点,在支撑平面布置中采取了双圆环支撑体系,施工中通过严密监测双环形支撑体系在施工过程中的水平位移、环形支撑轴力以及周边房屋倾斜值、竖向沉降变化情况,确保基坑施工期间工作人员、周边建筑的安全,从而保证基坑支护体系的稳定。
The article introduced the application of double-ring bracing system in a foundation pit in Sanya Hainan province. According to the environment surrounding characteristics of the foundation pit, double-ring bracing system was used in plan layout of support. By monitoring the displacement, axial force of annular support and tilt, vertical settlement value changes of the surrounding housing closely, the safety of operating personnel and the surrounding building was ensured. Meanwhile by doing this, the stability of foundation excavation was guaranteed.
