| Abstract: | By taking a self-anchored suspension and cable-stayed combination bridge with single tower and double cable planes as the research object,the test model of cable replacement was built up.Through the analysis of experimental results,the mechanical behavior and deformation regularity of self-anchored suspension and cable-stayed combination bridge during cable replacement were obtained and the structural safety was also analyzed.The result indicates that the method is correct and the cable replacement is feasi... |
