Abstract
Combined with engineering examples, in the case of a single-storey garage and a two-storey garage respectively, the foundation form of raft and column pier and anti-uplift pile （reduced settlement pile） is adopted, and the number of anti-uplift piles is calculated according to the anti-floating requirements; under-column compensation piles, four piles under the column are used in this project to balance the settlement in two directions; the method of inverted beam and girder floor is used to verify the high water level anti-floating requirements of the foundation; the composite foundation method is used to verify that the water level is below the foundation; strive to achieve reasonable calculations for both anti-floating and compressive working conditions. This method is a relatively simplified algorithm, but it relies on the refinement of parameters such as soil coefficient of subgrade reaction, pile stiffness coefficient, and cap effect coefficient.
