Differential settlement of composite foundation cannot be ignored, and often brings undesirable internal force to the structure. Traditional solutions are to change length, spacing, and diameter of the pile to achieve even foundation stiffness. Squeezed branch pile is a new type of pile with high pile capacity and low settlement. This paper simulates the interaction between squeezed branch pile and soil using the finite difference analysis software FLAC 3D, and get the best solution to reduce, or even eliminate, differential settlement, leading to a more reasonable structural arrangement.
