BRIDGE WITH PREFABRICATED SECTIONS AND WITH EXTERNAL PRESTRESSING BY CABLES,SECTIONS FOR THIS BRIDGE AND METHODS OF FABRICATED OF THESE SECTIONS

摘要

A bridge has prefabricated sections and is prestressed externally of the concrete of the sections by cables. Each section has upper and lower decks, interbraced by longitudinal oblique webs which form dihedrons. Certain dihedrons are closed by transverse panels. The panels assure the desired deviations of the prestressing cables as well as their anchoring.
