Abstract: Super high-rise buildings have high requirements on foundation bearing capacity and settlement control. This paper takes a super high-rise building project in Singapore as an example to study the pile foundation design of the building and the settlement of its piled raft foundation. This paper takes a high-rise building project in Singapore as an example. First, the geological conditions of the area were analyzed based on the soil investigate report and the corresponding geological parameters were obtained. Then a numerical model was established, and the settlement of the piled raft foundation of the super high-rise building was analyzed based on the numerical calculation results, and the pile foundation design parameters were reviewed. The calculation results show that the maximum settlement of the raft foundation is about 21 mm, which is less than the design requirement of 40 mm; the maximum differential settlement is 1∶1 400, which is less than the design requirement of 1:500; the existing six large-diameter piles bear a load less than the working load. Therefore, the design of the piled raft foundation of this super high-rise building meets the requirements of the specifications.
