摘    要:曲线梁能够适应复杂路况的需要,是现代交通工程中的一种重要桥型。但由于曲率的影响,曲线梁易产生弯扭耦合作用,因此曲线桥的内力、变形计算远比直线梁桥复杂,实际工程中易产生问题。文章系统阐述了曲线梁桥的常见病害及原因,提出了防止病害产生的处治措施,为曲线桥的维修与加固提供方法依据。

关 键 词:曲线梁桥  病害类型  原因分析  处理措施

Abstract:Camber beam can fit the needs of complex road condition and is an important bridge type in modern transportation construction.Due to the influence of curvature,camber beam is easy to cause crankle coupling effect.Thus, the internal force and deformation calculation of curved bridge is much more complicated than straight bridge, and easy to cause problems in real practices.The article systematically explains the common defects and reasons.It provides maintenance and reinforcement method for curved bridge.
Keywords:Curved bridge  Defect type  Reason analysis  Prevention
