摘　　要：由于曲率的影响,连续曲梁桥的内力、变形特点与直线梁桥不同,边界条件对结构受力影响显著。针对某连续曲梁桥在桥梁检测时发现的桥梁病害,通过有限元模型计算分析病害产生的原因,并给出了处理办法。本研究结论对改进连续曲梁桥的设计、养护及加固具有一定的理论与实践意义。The internal forces and deformation behavior of curved continuous bridge are different from that of straight-line bridge due to the impact of curvature.Boundary condition is very important to the mechanical characteristics.The bridge diseases found in the bridge inspection of a curved continuous bridge are introduced in this paper.The analysis of bridge diseases is conducted by means of FEM model,and then the treatment method is put forward.The conclusions obtained are obviously significant to theory and application for bridge design,maintenance as well as construction of such curved continuous bridge.
