Study and comparative evaluation between soils reinforced with geogrid and reinforced concrete walls for the stabilization of road slopes

Abstract

This research project is carried out with the aim of making a contribution to civil engineering in the areas of geotechnics and structures as well as costs and budget. It focuses on making a study and comparative evaluation both technically and economically between two systems that are: Soils Reinforced with Geogrid (Mechanically Stabilized Walls of Earth), as an alternative in the conformation of the surface of rolling on highways, in front of the Walls of Reinforced Concrete (Wall in Cantilever). As such effect was used: The basic engineering studies of the project Rehabilitation and Improvement of the Huancavelica - Lircay Highway, Section Km. 1 + 550 (Los Chancas Avenue) - Lircay, to be able to perform the respective calculations, and finally we conclude with a comparison of costs between both systems. It is concluded that Soils Reinforced with Geogrid (Mechanically Stabilized Walls of Wall (MSEW)) present economic savings in front of the Reinforced Concrete Walls in the stabilization of slopes in highways; In addition, the flexibility provided by MSEWs is due in principle to the materials with which they are constituted, this gives the possibility of accompanying the settlements of the foundation land; in addition to being backed with the greater FS to the volteo (with and without earthquake) that they present in the analysis of external stability; with which the technical advantage is emphasized in front of the cantilevered walls of Armed concrete, which are rigid structures.
