Settlement Of Tall Buildings Supported On Deep Foundations In Southeast Florida, USA

This paper presents different deep foundation systems and associated settlement records for high-rise building projects in the coastal areas of southeastern Florida. An introduction to the sedimentary soil and soft rock geology in coastal areas of southeast Florida is presented, and the deep foundation systems utilized include: piles of varying length, pile supported mat, preload and short piles, and drilled shafts. The implementation and associated settlement monitoring data of the different deep foundation systems are described through case histories involving 20 to 66-story buildings. In addition, the deep foundation systems and settlement monitoring results for twenty-one additional high-rise building projects in the coastal areas of southeastern Florida are presented.
