Diseño de una vía de tercer orden en el territorio del Proyecto SAHINO en Putumayo

Abstract

This work presents the geometric design of the road segment connecting Platform B and Platform F in Block 90 – Sahino. The study arises from the importance of this road as part of the project’s internal infrastructure, as it enables the movement of personnel, equipment, and supplies between both platforms. The design process began with an analysis of the site’s topography, identifying elevation changes and the actual ground conditions. Based on this information, the roadway alignment was defined, seeking to adapt the layout to the existing terrain while avoiding unnecessary interventions. At the same time, projected traffic was estimated for a ten-year period, which allowed the road to be classified as a low-volume facility (Class V) in accordance with current regulations. Using these criteria, the design speed was established, and both horizontal and vertical alignments were developed. In plan view, straight sections and curves were defined in compliance with the required minimum radii. In profile, longitudinal grades and vertical curves were adjusted to achieve smooth transitions and adequate visibility conditions. Superelevation and widening in curved sections were also evaluated, considering the circulation of heavy vehicles associated with the block’s operations. Earthwork volumes generated by the proposed grade line were analyzed to determine where greater terrain modification would be required and where minimal adjustments would suffice. This assessment made it possible to refine the profile and obtain a solution that is technically consistent and feasible from a construction standpoint.
