摘要：
Using the Jianninxia Bridge as the experiment object, we set dynamic loading test on it, and did theoretical analysis on its natural vibration characteristics by using large-scale general finite-element software. After the comparative analysis between the collected datas and the theoretical analysis datas, we find that the measurement of the natural vibration frequency is greater than the theoretical analysis value; and the measured value of impact coefficient is less than the theoretical value; therefore, it indicates that this bridge's actual structural rigidity is greater than its theoretical rigidity, but lack of the impact resistance.
