摘要:
旨在研究等截面圆弧无铰板拱桥梁在使用过程中的技术状况评定方法与针对已出现的病害所提出的加固方法的探索， 针对西安朱雀大街朱雀门桥，选用桥梁静、动载试验对桥梁的技术状况进行评价，结果表明，西安朱雀大街朱雀门桥应变校验系数在0.50～0.86之间，挠度校验系数也在0.53～0.75之间，均小于1；桥梁的一阶自振频率为17.27 Hz，大于理论计算的17.21Hz，整体结构的实测振动曲线与理论计算值基本相符，桥梁技术状况良好．
Abstract:
This paper aims to research the technical condition evaluation method of uniform-section circular hingeless plate arch bridge in use and explore the strengthening method to tackle the diseases that have appeared. Based on Xi ’ an Rosefinch Street gate bridge, this paper chose bridge static and dynamic load test to carry out bridge technical condition evaluation. Results showed that strain calibration coefficient of Xi ’ an Rosefinch Street gate bridge is between 0.50 ~ 0.86 while its deflection calibration coefficient is between 0.53 ~ 0.75 and both of them is less than 1. The first-order natural frequency of the bridges 17.27 Hz , greater than the theoretical calculation of 17.21 Hz, and the measured vibration curve of whole structure is consistent with the theoretical calculation value. All these results showed that the bridge technology is in good condition. For diseases that have appeared, this article put forward suggestions for strengthening. Results show that the technical condition of uniform-section circular hingeless arch plate bridge is good, but for diseases that have appeared such as cracks it needs specific reinforce maintenance.
