Análisis, diseño y presupuesto de una estructura de estabilización en la parroquia Salinas, cantón Ibarra, provincia de Imbabura

Abstract

This technical project has the purpose to analyze, design and budget a stabilization structure for Salinas Block 1 Educational Unit; located in Salinas parish, Ibarra canton, Imbabura province. Project's problem centers on the risk of a possible collapse of the slopes caused by heavy rains or earthquakes. This can threaten the lives of people in the community. For the selection of the stabilization structure, an analysis of the topography in the site is required to determine an adequate structure that is optimal and efficient based on the slope to be supported and the construction space. The cantilever retaining wall is the best option, taking into account the level of safety to be provided to the Educational Unit, and that the maximum slope to be covered in the project is 3.80 meters, so it is not necessary to place buttresses. The Slope Factor of Safety is calculated by the Bishop method and compared with the results obtained from the MIDAS software for the 7 existing profiles in the project. In the design stage, first a soil study is carried out to determine the soil characteristics such as: soil type, angle of internal friction, cohesion, bearing capacity of the soil, etc. This study is very important for the respective verifications to be carried out as recommended in the NEC-15 and ACI 318-14 standards that establish minimum values of safety factors that must be met both in the manual design and the verification using the MIDAS software. The project consists of 7 designs for all sections of the retaining wall. The designs include transverse and reinforced profile drawings, unit price analysis, technical specifications, budget and schedule of activities.
