| Abstract: | In light with the structural characteristics of the heavy-haul railway in China,large finite element software AN-SYS is adopted to establish the 3-dimensional model of the surrounding rocks-tunnel structure-track structure and moving load is applied to simulate the vertical moving load of the train with the focus on the distribution and transmission of the load of heavy-haul train on the tunnel subgrade as well as the spatial distribution of the internal force of tunnel structure. |
