Abstract
In a man-made island having total area of 436 ha was constructed a 12-storeyed steel-frame building with basement. Prior to construction of the building, the subsoils were improved by preloading. Settlement of the building during and after construction was measured. In the present paper, to ascertain charcteristics of settlement of the building and the ground, measurement results thus obtained are compared with those of settlement of the ground itself and settlement of another buiding constructed in the same site. 10 of the foundation piles were provided with a strain gage to measure long-term axial force of a pile. In the last part of the paper, change in loads acting on the piles is studied in connection with the measured groud settlement.
