ABSTRACT
ABSTRACT: Chiapas Bridge is located on Las Choapas – Ocozocuautla Highway, crossing the second largest dam in Mexico. To develop the constructive project, the site’s topographic-hydraulic, geotechnical, seismic risk, wind incidence, geological and geophysical studies were carried on. The substructure consists of 8 jackets formed each by 4 steel pipe legs, floated and sunk, through which big diameter concrete piles were drilled and cast in place. Superstructure is a steel box-girder deck, launched from one side with 168 m cantilevers.
