Estudio geotécnico e implementación de muros mecánicamente estabilizados para la ampliación a cuatro carriles de la carretera Alóag-Santo Domingo sector la Esperanza (Abscisa 54+710-54+870)

Abstract

Abstract: Retaining walls are structural elements whose function is the stabilization of natural slopes. However, new soil containmentsystems have been implementedcomparedto traditional systems. A practical application is the implementation of mechanically stabilised walls for slopes and embankments for road widening.This system contemplates the use of geosynthetics, arousinggreat interest inthecurrent construction, in addition to the advantages in the economic and time order, this system has proven to be justasefficient as concrete walls. In this way, the main objective of this research was to carry out a geotechnical-geological study for the MSE design of the Alóag -Santo Domingo Highway, La Esperanza sector, based on the information available from Hidalgo e Hidalgo Company, whose analysis process can be applied as a design guide for sectors with similar geotechnical characteristics. Through this research project, it was established that the MSE with geosynthetic geogrids uniaxial UX 1500 and biaxial BX 1200, presents a cost benefit of 36.67% less compared to the reinforced concrete wall.
