| Abstract: | With the development of urban road and highway traffic,the curved girders are increasingly widely applied as an important bridge style in modern communication engineering.Based on engineering project,this paper calculates and analysis the influence of bearing characteristic of continuous girder bridges with singleK-column by setting eccentric distances.The results show that both curved girder ＇s torque distribution and side timbers＇ toque value has been improved,and also this paper put forward some rational principle of eccentric distances setting for curved continuous girder bridges＇ designs. |
