| Abstract: | The paper analyzed the stress characteristics of simply supported beams, continuous beams and the statics and dynamics characteristics of simply supported-continuous bridge of single-bearing, flexible double bearing and rigid double bearing. Using spring elements to simulate the double-bearing simply-supported continuous beam bridge, through the comparative analysis of specific project examples measured data and the simulated data, the paper proves the feasibility of flexible double-bearing model. |
