| Abstract: | Based on stress analysis of single-column pier of curved bridge with different curve radius under differ- ent eccentricity, the relation between torque and eccentricity has been obtained, so, the reasonable eccentricity of single column pier could be determined on the basis of the curve radius of curved bridge, which could effec- tively adjust the torque distribution of finished curved bridge and improve safety and economy of design for curved bridge. |
