Evaluación del fenómeno de erosión, mediante la construcción de un modelo reducido para suelos arcillos de la formación Tilata (Tst) en la ciudad de Tunja - sector pirgua.

Abstract

In certain types of soils the erosive processes cause accelerated disappearance of the soil. Depending on the geotechnical and precipitation characteristics, the presence of gullies can be caused; deteriorating the stability conditions of some areas. There are studies for erosion control where the majority are tests carried out in the field. However, there are no specific studies for the analysis of soil loss in the gullies of the city in the pirgua sector. However, for the present investigation, the use of samples in the northwestern area was taken into account. Bearing in mind the erosive processes that have been generated in the Tilata formation (Tst) to carcavation problems; It is intended to carry out an evaluation of the loss of soil; caused by factors such as precipitation and topographic conditions in the area. For this reason, it is necessary to study the relationship between the phenomenon of soil erosion and the type of material found in the Tilata formation (Tst) in the Pirgua village in the Northwest zone. To this end, the objective was to create an original channel type prototype; in reduced dimensions; in which this phenomenon can be modeled by controlling variables such as precipitation and the slope of the model. It is expected to obtain results from the models that allow knowing the rate of loss of the material adjusting as much as possible to the real conditions that can occur in a gully.
