| Abstract: | In order to inspect the actual status and performance of the bridge across the Li River available at Guilin Shijia ferry and provide scientific basis for the project acceptance, it was statically and dynamically tested and analyzed with finite element method, and its technical performances are calculated and analyzed. The test covers the deflection and stress of the main sections, natural frequency, impact coefficient and damping ratio, etc. The result indicates that the bridge has a high quality of design and construction, and its work condition and all mechanical performances of this bridge can meet the requirement of the codes and design. |
