| Abstract: | Taking Shijialiang Tunnel project along Chongqing Belt Highway as the example,the paper analyzes the influence of the newly-built road tunnel construction on existing railway tunnels by simulating the three-dimension spatial numeric calculation of the tunnel,identifies its influential scopes on the railway tunnel,undertakes the internal force calculation and the safety evaluation of the structure within the influential scope,and proves by the result that the safety coefficient of the tunnel structure meet the regulation demands. |
| Keywords: | road tunnel railway tunnel numeric calculation influential analysis |
