Pile foundation settlement can affect nearby high-rise buildings. The study looks at how single piles and groups of piles settle. By using static pressure sinking pipe cast-in-place piles, soil squeezing can occur during construction. The researchers conducted experiments and simulations to see how pile settlement impacts adjacent buildings with and without raft foundations. Comparing simulation results with real measurements helped validate the accuracy of the simulations. The study focuses on understanding and solving issues related to pile foundation settlement on surrounding buildings.
