摘要
介绍了型钢和钢筋混凝土两种不同材料组合而成的环形支撑体系在某基坑工程中的成功应用。根据本基坑组合结构环形支撑体系的特点,在支撑平面布置中采取了相应措施;施工中通过严密监测环形支撑在不同施工阶段的位移、轴力变化情况,分析得出环形支撑梁位移、轴力变化特点及原因,采取有针对性的处理措施,从而保证了基坑支护体系的稳定,确保基坑内作业人员的安全以及周边道路、地下管线及建筑物的安全。
The authors introduce the application of annular bracing system with steel and reinforced concrete combined into combined structure in some foundation excavation engineering.According to the characteristics of annular bracing system with combined structure,some corresponding measures are taken in plan layout of support.By closely monitoring the displacement and axial force change of annular support in different construction stages,the authors analyze the changing characteristics and reason of the displacement and axial force of annular support beam,the pertinent measure is taken to ensure the stability of foundation excavation system,the safety of operating personnel in foundation excavation,the safety of peripheral roads,underground pipeline and buildings.
