Abstract (Spanish)
En Bogotá existe un depósito lacustre con espesores de 500 m al occidente de la ciudad. En los últimos años, con la renovación de la infraestructura de la ciudad, se han promovido diferentes técnicas de exploración y ensayos en suelos blandos, siendo el más utilizado el piezocono (CPTu). A partir de este ensayo y mediante funciones de correlación, se realizó la medición de la variabilidad espacial, estimando las escalas de fluctuación en tres zonas de la ciudad. Se encontraron valores menores en aquellas zonas donde el gradiente de sedimentación es alto, es decir cerca al piedemonte de los Cerros Orientales. La medición de la variabilidad especial se realizó tanto en el sentido vertical como en el sentido horizontal, observándose una alta dispersión en los valores obtenidos en este último. Este trabajo busca contribuir a la base de datos sobre la variabilidad estadística en arcillas lacustres, con el fin de ser utilizadas en análisis de confiabilidad para futuros proyectos que se desarrollen en la ciudad.
Abstract (English)
In Bogotá, there is a lacustrine deposit with thicknesses of up to 500 meters in the western part of the city. In recent years, as the infrastructure of the city is being renovated, various exploration and test techniques have been promoted in soft soils, with the piezocone (CPTu) being the most widely used. Based on this test and the use of correlation functions, spatial variability was measured by estimating the fluctuation scales in three areas of the city. Smaller values were found in areas where the sedimentation gradient is high, i.e., near the foothills of the Cerros Orientales. The measurement of spatial variability was conducted in both vertical and horizontal directions, with a high dispersion observed in the values obtained in the latter. This study aims to contribute to the database on statistical variability in lacustrine clays, with the purpose of supporting reliability analyses for future projects to be developed in the city.
