Analysis of basic design of reconstruction and expansion projects
In a project with multi-storey basement,the construction scheme was adjusted greatly in the construction process,and the in-ternal force of the column bottom increased greatly.The foundation slab of the original scheme has been completed,and the foundation part has passed the acceptance.Through theoretical derivation and calculation analysis,the favorable water buoyancy was studied,and a rea-sonable safety factor was formulated to derive the actual stiffness of the foundation pile.The compressive bearing capacity of the pile foun-dation,the bearing platform and the pure pull-out pile was analyzed,and the overall performance of the foundation slab was guaranteed to the greatest extent under the premise of ensuring the safety of the building structure.
