Abstract
The primary consolidation settlements in soils under pressure due to raft foundations were evaluated using the Excel DISBAL book, and the results of the classical procedure for calculating primary settlements, taking into account the soil compression index, were compared with those of the simplified procedure based on the summation of layers method, recommended by the current Cuban standard of surface foundations. The novelty of Excel DISBAL book is its contribution for solving shortcomings of software based on current geotechnical methods and in accordance with the legal framework of current construction regulations in Cuba and other international references. The case study deals with the evaluation of the extension in height of a building supported in soil deformation limit state and hypothetically located in the experimental field of Civil Engineering of Universidad de Oriente, where the coves were made by the National Research Company Applied from Santiago de Cuba. It is demonstrated that this software allows an adequate assessment of the limit state due to soil deformation by both methods, obtaining acceptable primary consolidation settlements for the case study, and helping to specify the number of floors the building will reach.
