1 工程概况 主楼位于健康路7号,地面以上20层,地面下两层建筑;埋深6m～8m底面积43.2m×23.4m,布钻孔灌注桩400根。桩心距1.80m呈方格形布桩。桩径600mm,有效桩长27.0m,为摩擦桩。在标高-87.m～-35.7m成桩。根据工程地质勘察报告提供土的计算参数,预估在满足上部荷载的单桩竖向承载力标准值为1652KN。 由于该地基基础属一级安全等级,按《建 1 Project Overview The main building is located at No. 7, Jianshe Road, with 20 floors above the ground and two floors below the ground; the depth of 6m to 8m is 43.2m by 23.4m and there are 400 cast-in-place piles. The pile center distance is 1.80m. The pile diameter is 600mm and the effective pile length is 27.0m. It is a friction pile. Piles were made at elevations of -87.m to -35.7m. According to the calculation parameters of the soil provided by the engineering geological survey report, the standard value of the vertical bearing capacity of a single pile meeting the upper load is estimated to be 1652 KN. Since the foundation is a Class I safety rating,
