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 ?). 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.
