Efecto del porcentaje de diatomeas en la curva compresibilidad del suelo

Hernandez Manrique, Yeison (Escuela Colombiana de Ingeniería Julio GaravitoIngeniería Civil, 2019)

This paper presents the results of the consolidation of a diatomatic soil with different percentages of diatoms. The objective was to find considerable differences in four reconstituted soils with 0, 25, 50, and 75% of ...
Estudio de la formación de fisuras de desecación por medio de fractales

Vija Arévalo, Egna Katherine; Martinez Ortiz, Laura Daniela (Escuela Colombiana de Ingeniería Julio GaravitoIngeniería Civil, 2020)

In this paper were analyzed the desiccation cracks produced in a clay soil using fractal mathematic. This soil, composed of Kaolin and Bentonite, was studied in four different sizes of mold, with the aim to know how is the ...

This paper presents the results of the consolidation of a diatomatic soil with different percentages of diatoms. The objective was to find considerable differences in four reconstituted soils with 0, 25, 50, and 75% of diatoms, through tests such as Atterberg limits, specific gravity and consolidation using the automated oedometric Consolidaometers of the Julio Garavito Colombian School of Engineering . In addition to these tests, four flights are carried out in the centrifuge at 200 graves at a slope of 45 degrees modeled on the consolidation boxes of the four floors. The results indicated in the liquid limits and in the gravity specify some variations as the percentage of diatoms increases, on the other hand, with respect to the compressibility characteristics of the soil, the compressibility index did not have considerable changes and the flights in the centrifuge not determined a defined fault plane

In this paper were analyzed the desiccation cracks produced in a clay soil using fractal mathematic. This soil, composed of Kaolin and Bentonite, was studied in four different sizes of mold, with the aim to know how is the influence of this parameter in the formation of the cracks, having as a result, a numerical characterization of a chaotic phenomenon, which is relevant in clay soil in dry seasons.Subsequently, this result could be associated with the properties and parameters of the soil, thus knowing the cracks response to environmental factors, the mineralogy composition of the soil and other factors. Conducting a fractal analysis through box counting method, it is found the fractal dimension of a mold in a specific time, which is going to be related not only to the others molds, but also to the others monitoring times, with the intention to discover the relations that bind together the time, the size and the fractal dimension. The main connections that were identified are: the ratio among the fractal dimension and the size of the mold is inversely proportional, and the ratio among the fractal dimension and the cracking time is directly proportional.
