This research was developed in order to study, identify and evaluate soil types that exist in the Coperholta sector and also determine their bearing capacity. By applying the fundamental concepts of soil mechanics. This study was based on the results obtained after running the respective exploration and soil sampling as indicated in the Standard E050 of the National Building Regulations. Exploration samples, which were subjected to the respective trials and the results gave us the physical and mechanical characteristics that have these soils so they can make their classification were obtained, and with the contribution of shear test parameters were obtained the friction angle and cohesion are basic factors to determine the bearing capacity of soils. Thus using the theory of Terzaghi for the type of local failure for square foundations, the bearing capacity of soils Sector Coperholta was ...
