| Abstract: | In this paper the calculation method of expansion and contraction force is introduced for jiontless rail on bridge. And according to former experimental and calculation results, the differential relationship between rail displacement and expansion and contraction force the displacement function is acquired as well as the expected solutions based upon boundary conditions of structure and compatibility condition of deformation. |
