ORDAZ HERNANDEZ, Alexis. Contribution to the management of urban risks in Pinar del Río city using a 3D geological-geotechnical model. Min. Geol. [online]. 2017, vol.33, n.4, pp. 423-440. ISSN 1993-8012.

The objective of this paper is to elaborate a geological-geotechnical model in three dimensions for the Cenozoic section which is the shallowest of Pinar del Rio City. It is intended that the model obtained is used in future as an interpretative basis for geotechnical phenomena arising in the urban environment. The procedure fallowed can be easily applied to other worldwide studies, mainly in the areas that exist a big volume of geotechnical information. The procedure fallowed can be easily reproduced in other study cases worldwide, specifically counting on a wide volume of geotechnical information. Six Engineering Geological Types (EGT) are identified in the model, namely, Artificial fill, Vegetation layer, Marine alluvial coarse grained soil, Marine alluvial fine grained soil, Eluvial soil and Bed rock. The 3D geological-geotechnical model illustrates the spatial arrangement of the EGT above, and can contribute significantly at decision making in urban planning.
