摘　　要：结合无锡地区某环形支撑地铁车站深基坑监测数据,分析了地下连续墙受力变形规律,并推荐了无锡地区环形支撑地铁车站基坑围护结构受力变形的合理计算方法,对比分析了支撑内力的监测值与计算值,验证了环形支撑的较好整体稳定性和协调性。Combining with the monitoring data of a ring-shaped support metro station deep excavation in Wuxi area,we analyzed the forced deformation regulations of the underground diaphragm wall.The appropriate forced deformation computing method for the ring-shaped support metro station deep excavation in Wuxi region was suggested.Comparatively analyzing the monitoring values and calculating values of support force,we verified that the stability and overall coordination of ring-shaped support were very well.
