| Abstract: | The dynamic coefficients of railway continuous bridge under high speed trains and the stability of trains are studied. The study results show that the dynamic coefficients of continuous bridge and train stability are smaller than those of simply supported bridge, and the dynamic coefficients for design are proposed. By analyzing the dynamic responses of continuous bridge when the spans are unequal, the method for calculating dynamic coefficients is discussed. |
