Crocodiles Protection: Impact for Chambal River Bridge Design

摘要

This bridge, the first axial suspension cable-stayed bridge in India, had to meet some challengingrnrequirements for the protection of crocodiles in the Chambal river.rnIn order not disturbing the crocodiles, modern and specific techniques had to be used for the design.rnBed rock profile and deposit thickness below water were mainly determined by using satelliternimagery. Geophysics using a resistivity method was implemented in order to assess the weatheredrnzones on a large scale. A 3D model of the cliff at pier P5 was elaborated.The design of the noisernbarriers shape required wind tunnel tests, in order to limit vortex-shedding vibrations.
