| Abstract: | In this paper, a bottom-road concrete tied arch bridge which main span is 86.1 m is tested under static and dy- namic load. According to the bending moment envelope of the bridge under live load, the key section is determined, through analysis of bridge key section deflection, stress is compared between measurements and theoretical values, the bearing capac- ity of the bridge is evaluated. At the same time, dynamic characteristics of the bridge is analyzed through dynamic load test. |
