Geotechnical Evaluation and Sizing of the Reinforcement Layer on Moles in the North Triangle Clover Project, in Brasília/DF, Brazil

The increase of the fleet of vehicles makes the Engineering is dynamic in solutions for the traffic flow. In Brasília, Distrito Federal, Brazil, it is no different. The city was designed for 500 thousand inhabitants, and currently, in the metropolitan region, circulate near 3 million. The growth of the city to a northern region, led to the development of a road complex called “Trevo de Triagem Norte” (TTN), composed of vehicles, road access, creation of new tracks and duplication of the Bridge of Bragueto on the lake Paranoá, giving access to the BR-020, as a solution to constant congestion. In the geopedological context, in the region, there are stretches with hydromorphic soils and water level at some times of the year. In geotechnical terms, soils are usually soft. Thus, this work presents a geotechnical evaluation of a region, but also the dimensioning of the reinforcement layer on the soils constitutes an end of future pathologies.
