Saint-Venant was a student at the Collège de France and the lecture notes he took in Liouville's 1839-40 class still survive. He taught mathematics at the École des Ponts et Chaussées where he succeeded Coriolis.

Saint-Venant worked mainly on mechanics, elasticity, hydrostatics and hydrodynamics. In the 1850s he derived solutions for the torsion of noncircular cylinders. He extended Navier's work on the bending of beams, publishing a full account in 1864. In 1871 he derived the equations for non-steady flow in open channels. He also developed a vector calculus similar to that of Grassmann.
