摘要
独柱墩曲线桥受力机制复杂,受曲率的影响,易产生弯扭耦合作用。曲线桥产生的病害以及病害特征与直线桥有较大不同。依据某立交桥G线匝道桥的现场检查,阐述了曲线桥常见的病害,并对病害成因进行了分析。结合具体工程,介绍了曲线桥病害处置的加固方案。
Mechanical behavior of curved single-column-supported bridge is complicated.It is easy to produce bending-torsion coupling for curved bridge due to the influence of the initial curvature. Compared to straight bridge,there are relatively big differences on disease and disease characteristics of curved bridge.The paper is based on field test of G ramp bridge of an overpass.Common disease of curved bridge is expounded and disease genetic is analyzed.According to diseases and disease genetic,reinforcing measures are introduced to treat diseases with the concrete engineering.
