| Abstract: | According to the principle of the interaction between the beam and the CWR (continuously welded rails) that the longitudinal forces of CWR on railway bridges are passed on to the piers by the span structures of the bridge, the intensity of piers is checked up by calculating and the safety reservation is analyzed so that the design of the CWR on railway bridges is optimized and is safer and more economic. |
