摘　　要：上海东兰小区A-2地块商务楼基坑支护工程基坑深10.6m,地质条件复杂,采用钻孔灌注桩加两层钢筋混凝土圆环支撑进行支护,一排三轴深层搅拌桩止水。圆环支撑直径92m,是上海少有的大直径圆环支撑。对计算结果和实际监测结果作了对比分析,得到了一些有益的经验。A 10.6m-deep foundation pit of Donglan Community in Shanghai,in complex geological conditions,was upheld by drilling-grouting pile and two concrete circular bracings.The diameter of this circular bracing is 90m,and it is rarely seen in Shanghai.Compared the results of the numerical analysis with the measurement,we got some useful conclusion from the project.
