Abstract

Models are widely used in all sciences to simplify the most complex problems in reality, allow a representation of the behavior of a system and acquire great relevance in Geological Engineering.The conceptual geological model is very useful for projects developed in the field. Geotechnical models have evolved in parallel to computer-assisted techniques, from 2D to 3D models. The correct modeling of the physical-mechanical properties contributes to obtaining a representation of the characteristics of the geological object.The low availability of soils in the city of Caimanera, province of Guantánamo, appropriate for construction, has forced the use of swamp areas for urban development, through the use of low-thickness fill materials. The execution of constructions on swamp areas and low plasticity soils contributes to the increased risk of liquefaction.The 3D model obtained allowed the approximate spatial distribution of the variables (liquid limit, natural humidity, number of blows of the standard penetration test, percentage of fine soil and plasticity index) that affect the susceptibility of the soils in the area. Caimanera power station.The results of the 3D model indicate that the soils represented by compressible clays, silty clay, calcareous shale and organic silt have a high susceptibility to liquefaction; and that the compressible clays located in the University Venue have the highest susceptibility to liquefaction, taking into account the relatively low fines content (14%).
