Foundation Design for High-Rise Tower in Karstic Ground
Ground investigations for a high-rise tower in Jeddah Saudi Arabia revealed the presence of cavities in some of the boreholes. It was decided that a piled raft would be a suitable foundation option as it would provide a measure of redundancy in case some of the piles encountered cavities. Under such circumstances, the raft would permit the transfer of load from the affected piles to those founded in sound limestone. This paper sets out the design process adopted for the piled raft foundation and describes the post-design analyses undertaken to investigate the mechanism of load transfer from cavity-affected piles. Comparisons are made between the behavior of the piled raft when no cavities are present and that when cavities are randomly encountered by some of the piles. The increases in pile axial load and raft bending moments in such circumstances are presented.
