Plan de Mejoramiento vial, sector vía antigua al llano Km83+300

Abstract

The entry to the plain derives from the Eastern Mountain Range, which has experienced significant stability problems due to rainfall, mountain drilling through tunnels, and new road layouts on the dual carriageway. Converting this route is one of the most important in terms of transportation for the economy that reaches the capital of the country. The site "Rompe Ejes" is located at abscissa 83+300. It is a place located within the geography of the Meta Department, which has been greatly affected due to its susceptibility to continuous rainfall and seismic activity. The high precipitation dates to 2017, with the arrival of the famous "El Niño" phenomenon that occurred in the months of late April, May, and June. Causing multiple economic damages to the region and the municipality of Villavicencio. With the phenomena, mass removal phenomena were triggered in the Rompe Ejes sector (km 83+300), which have been studied and graphed on maps showing soil type, geomorphology, terrain slope, geotechnics, geology, among others. And likewise, with the help of this information, propose engineering solutions. With the researched material at IGAC (Agustín Codazzi Geographic Institute), the topographic composition of the areas was analyzed using duly georeferenced maps to assess the type of soil on which the structure will be designed. This sector has also been heavily affected by road embankment, reducing its space to a single lane, which minimizes vehicle passage, restricted only to private vehicles and special camper services, connecting the Pipiral village with the municipality of Villavicencio. This bridge, which spans 35m, will encompass the road embankment and will aim to provide a safe passage, with its foundation and load analysis. It is a complex area because adjacent to the zone, there are active geological faults that generate seismic activity.
