Construction of the wall of the k128 Alto Magdalena way, with site material and monodirected geotextiles.

The design of soil reinforced walls is a topic of special importance in the development of infrastructure projects, mainly because of the possibility of using materials from nearby excavations, which, without the use of Geotextiles, could not be used as filling material allowing compensated designs and minor environmental effects.
In this work, was studied different configurations of the structure, different inclinations of face and how they faced site conditions not initially planned in the approach of the bridge that was replaced with a soil reinforced wall, which would allow the construction of the road structure.
To understand the contribution of the inclusion of the Geotextile, different modeling were carried out looking for minor deformations, improving the construction processes and a stable and durable structure without the need for deep foundations. The modeling was carried out with monodirectioned geotextiles, reducing costs and allowing greater resistances to be used, based on an understanding of the mechanical functioning of the structures.
The filling material of the wall came from the excavations adjacent to the construction site, so the design was adjusted to the mechanical properties of the available material, without the need to import materials from distant sites.
