- Bearing capacity of footings in unsaturated soils employing analytic methods Jenny García Tristá Willian Daniel Cobelo Cristía Gilberto Julio Quevedo Sotolongo Ingeniería suction the soil Bearing capacity unsaturated soils water characteristic curve The study of the behavior of unsaturated soils has been the subject of several studies in recent years. The objective of this paper is to summarize the main aspects and different theories established by reference authors, used to estimate bearing capacity of unsaturated soils. The variation in the bearing capacity of a square shaped foundation surface: sides B = L 1.5 m is obtained, using the approach proposed by Brinch-Hansen considering the formulations offered by Fredlund and Vanapalli to estimate the unsaturated soil strength parameters (c and φ). Each of the reviewed formulations suggests a law of variation of cohesion values depending on the unsaturated suction function. A comparison of the behavior between the unsaturated and the saturated phases, is performed, using different values of matric suction obtained by means of the soil retention curve of Formation Capdevila. 2017 artículo científico 0122-3461 https://www.redalyc.org/articulo.oa?id=85252030009 https://www.redalyc.org/journal/852/85252030009/ https://www.redalyc.org/journal/852/85252030009/html/ https://www.redalyc.org/journal/852/85252030009/85252030009.epub https://www.redalyc.org/journal/852/85252030009/movil en http://www.redalyc.org/revista.oa?id=852 Ingeniería y Desarrollo application/pdf Universidad del Norte Ingeniería y Desarrollo (Colombia) Num.2 Vol.35
