Item Evaluación del esfuerzo cortante mediante el ensayo de corte directo en suelos limo-arenosos de la parroquia Quisapincha(Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Civil, 2024-08) Manotoa Paredes, Pablo Daniel; Pérez Maldonado, Ruth LorenaThe direct shear test provides the values of the internal friction angle and cohesion of a soil, values that are often assumed or neglected as the cohesion in the soils of our Andean region. The present research aims to evaluate the shear resistance of the soils of the Quisapincha parish through laboratory tests. Before starting laboratory activities, a reconnaissance of the areas where the sample was obtained was carried out, the sampling was carried out according to what is indicated in the corresponding regulations, pits were used to extract samples, once the desired depth was reached, He began to carve a sample block to obtain a complete sample; To characterize the soil, humidity, granulometry, and Atterberg limits tests were carried out. With the results, the soil type was classified according to SUCS and AASHTO. To obtain the shear resistance, direct cutting equipment was used, 3 specimens were carved for each sample and the test was carried out, a normal stress of 50 kPa, 100 kPa and 200 kPa was placed, the internal friction angle values and Cohesion range from 23.671 degrees to 39.26 degrees, while cohesion values range from 0.44 to 1.24 kilograms per square centimeter. The shear resistance values range from a minimum of 83.726 kPa; 124,593 kPa and 171,472 kPa respectively at the normal applied stress and up to maximum values of 159,996 kPa; 200.863 kPa and 282.595 kPa.Item 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(Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Civil, 2019) López López, Luis Rafael; Pérez Maldonado, Ruth LorenaIn 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.
