Abstract: Based on the structure analysis of practical project, the support conditions have been considered emphatically. The improving measures for resistance to torsion of bearing have been concluded for small radius curved continuous bridge. The measures can guarantee that the inside support of curved bridge will without gap between bearing with pile.

Key words: curved girder bridge, bearing for torsion, linear eccentricity, reservation for pressure
