| Abstract: |
The “Autopista Urbana Siervo de la Nación” (AUSN) Highway, is located at Mexico City, and is currently under construction. The highway, with a length of 14.5Km and 4 lanes divided in 2 carriageways (A4 type cross section), intends to target the milestone of a fast and safe road axis. The available right-of-way to built the new infrastructure presents several restrictive constrains that led to the construction of a flyover throughout approx. 90% of the AUSN total length. The unique geotechnical scenario that characterizes the Valle de México’s lake zone, with the well- known regional settlement phenomena, along with the peculiar features that define the seismic action within the “lacustres” areas of the city, associated with high structural response amplification, lead to complex structural solutions and demanding calculations, particularly concerning the foundation´s design, optimizing the structure behaviour and minimizing the global costs during all the infrastructure’s life cycle. |
