Load tests were carried out on the Canglang Plug River Bridge in Zhushan County,where two spans were selected for loading and analyzed using Midas finite element software.The results showed that the loading efficiency ranged between 0.96 and 0.99,and the box girder deflections and strains were within the safe limits,indicating that the bridge possessed good stiffness and strength.The dynamic load test further verified the stability and safety of the bridge under dynamic loading conditions.The dynamic response and self-oscillation characteristics exhibited under vari-ous working conditions were excellent,demonstrating that the overall structural technical status of the bridge is good,and thus,it can be safely put into use.
