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.
