| Abstract: | Based on the calculation theory of the continuous weld rail （CWR） track on bridge, in connection with its breaking mechanism, considering the influence of adjacent non-broken rail and pier stiffness, the analytic calculation meth- od of additional force acting on bridge due to breaking of the CWR is derived and analyzed compared with the finite element solution, it is shown that the theoretical analysis calculatiorl method is correct. And this method makes the calculation of additional force acting on bridge due to breaking of the CWR more reasonable. Moreover, it can guide the design of the CWR track on bridge. |
