Bogotá, the capital of Colombia is located in a plateau on the Eastern mountain chain of the Andes, whose subsoil is conformed by a quaternary lacustrine deposit conformed mainly by layers of clays and silts with sand interleaves. The soft clays, present in a considerable area of the urban and potentially urban zone, must carefully be studied so that the foundations solutions guarantee the stability and functionality of civil works. The study of constitutive models has had great evolution in academic means but its practical application in the design has been limited, mainly by its little diffusion and the necessity to use a greater number of parameters than the required ones in the traditional methodologies. The fundamental concepts of the Modified Cam-Clay (CCM) model, the necessary parameters and the capacity of the model are analyzed to reproduce the experimental results of a set of triaxial tests on reconstituted samples of Bogotá. Finally, the conditions under which the model better simulates the behavior of soil (normally consolidated) are identified and on which variables more work has to be done to obtain a more complete constituent model (anisotropy). ; Bogotá, la capital de Colombia se encuentra localizada en un altiplano sobre la cordillera oriental de los Andes, cuyo subsuelo está conformado por un depósito lacustre cuaternario conformado principalmente por capas de arcillas y limos con intercalaciones de arenas. Las arcillas de consistencia blanda, presentes en una considerable área de la zona urbana y urbanizable, deben ser cuidadosamente estudiadas para que las soluciones de cimentación garanticen la estabilidad y funcionalidad de las obras civiles. El estudio de modelos constitutivos ha tenido gran evolución en los medios académicos pero su aplicación práctica en el diseño se ha visto limitada, principalmente por su poca difusión y la necesidad de utilizar un mayor número de parámetros que los requeridos en las metodologías tradicionales. Se presentan los conceptos fundamentales del modelo ...
