Estudio del comportamiento de hormigón lanzado en la estabilización de taludes, para suelos limosos con pendientes mayores a los 60 grados en el km 2 + 240 en el paso lateral del cantón Ambato provincia de Tungurahua

Abstract

In the present project, began with the sampling of the slope, which is located in the lateral passage of the Ambato Town, these analyzes were developed in the soil laboratories of the Central University of Ecuador (UCE), applying ASTM standards: Granulometry ASTM D422, Humidity ASTM D2216-10 and Direct Cut ASTM D3080, being necessary to obtain the angle of friction and the cohesion of the slope floor, which allow us to obtain the safety factor (FS). The safety factor (F.S) was determined with the method of Fellenius or the same slices that were made in the Excel spreadsheet, programmatically. With the FS obtained, it was determined that the slope is unstable since it gave us a lower value than allowed (FS <1.5) within the stability required for it, since the soil composition is also of very low quality (sandy-silty ). With the analysis of the slope, it was determined that it must be stabilized by the use of the concrete released, since it lends great stability to slopes, walls, etc., and prevents future landslides from occurring, since due to Its excellent stability performance is highly recommended for such work. Ways of how to place and with which other structural elements to combine are indicated, such as: electro-welded mesh and anchors, which further help the stability of the slope. It was determined that the behavior of the concrete thrown on slopes is excellent since it almost immediately prevents landslides, and thus avoids future problems within the road.
