| Abstract: | According to the background of the old bridge reconstruction project at the south bank of Ziya New Bridge in 205 National Highway, the dynamic test is implemented for the double-column bridge pier after the dismounting of beam structure separately to measure the self-vibration frequency and vibration type of bridge transverse, longitudinal and turning directions. At the same time, the model amending method and the system distinguishing method are used to evaluate the working state of bridge pier by importing the measured mode data. |
