Estabilidad de talud de material suelto mediante la tecnología de tierra armada en el sitio Dos Bocas, cantón Atahualpa

Abstract

The slopes reinforced by means of elements that help the soil have more capacity where we can obtain benefits, such as gaining area for right of way, are low cost, easy to build, have been tested in real way before seismic events in Japan, large capacity of absorbing the forces of earthquakes, this technology is increasingly developed more and more, with more products and configurations. Reinforced floors have configurations such as extensible, inextensible, spiked, mixed, among others, for this investigation we focus on reinforced soils with extensible reinforcement, which must be deformed to obtain stability, as part of its configuration they carry drains , bags of black soil for vegetation, Foundation with a structure of Concrete or Stone, in some cases it is necessary to use piles, that depends on the bearing capacity of the soil, and the strata thereof. The problems presented in the winter season in the upper part of our province, are frequent landslides, where the road is obstructed. Losses range from economic to human lives. These events are derived from the poor stabilization of soils or other factors involved in them. A priority in road projects, in areas where the topography is complex should be the stabilization of walls, slopes so as to ensure that they will not suffer any type of landslide. In this document we will talk about reinforced soils, exposing several authors who have performed innumerable experiments, laboratory tests to determine the behavior of reinforced soil technology under different circumstances, with the data obtained in the soil laboratory we will make a preliminary design using the GEO5 demo version tool. The authors that we will mention carried out from walls to scale inside a box, suitable with sensors and other accessories, also walls of 1 1 scale or real scale, these studies are carried out in order to have a clear way of seeing how the behaviors behave. reinforced soils to the different factors that are in place, such as infiltration, earthquakes, rain, wind, corrosion, among many more. Like all structures, reinforced soils have several configurations which depends a lot on the topography of the land, where it is reinforced with metallic, geotextile elements, among others. With regard to GEO5, the necessary steps to make the correct data entry are shown, and the analysis, where the design is obtained in general, these structures are accompanied by drainage systems, to avoid erosion and soil saturation. For these analyzes we use the Reinforced Floor module and the Slope Stability Module, where the results were obtained such as wall geometry, thickness of each layer, external stability balance verification, bearing capacity verification, internal stability verification , determination of global stability, all this is reflected in this work, this research is carried out in order to implement in the construction field this technology that works very well, has already been proven, analyzed, is still being investigated to have more Information on their behavior, the manufacturers of geosynthetics on their web pages, have templates to calculate and know what type of reinforcement to place, as technology advances, it is easier to obtain information on how to solve problems such as slope stabilization, construction of tracks, retaining walls, construction of bridges, among other diverse to aplications
