Forecast of Settlement of Large-Size Foundations at High Pressures on the Base

Relevant issues are the construction of the foundation of structures with high values of mean pressures under the foundation base. At P_IImt reaching 680 kPa, the average settlement of the structures reaches S=200–580 mm. At the same time, vertical displacements sharply increase, after overcoming the average pressures constituting P_IImt=250–300 кПА. Herewith, from 60% up to 70% of deformations of the bases occurs during the construction, and the rest 30%–40% – after the installation of the structures. With such high values of average pressures and settlements of foundations, the projected values of the vertical displacements of these structures during subsequent periods of their operation are of no small importance. The logarithmic function S_t=S₀+A ln(1+Bt) is a successful mathematical dependence for the prediction of settlements of foundations at any subsequent period of time.
