摘要
随着城市道路和公路交通的发展,曲线梁桥应用日益广泛,已经成为现代交通工程中的重要桥型。从工程实际出发,计算分析设置预偏心对曲线梁桥受力的影响。分析结果表明,设置预偏心对曲线梁桥的转矩分布和端横梁处的转矩值均有改善,并提出了曲线梁桥设计时预偏心合理设置的原则。
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.
