| 中文摘要: |
| 近年来，随着我国铁路交通的大规模建设，新建铁路以隧道的方式下穿既有铁路越来越多的出现且在大量的工程当中且影响越来越严重。结合京石高铁下穿既有石德铁路工程，对下穿隧道暗挖段进行了数值模拟计算，分析研究了隧道下穿施工时对既有铁路路基沉降、轨道沉降、轨道水平偏差及轨向偏差的变形规律，得出了隧道下穿施工对既有铁路线路的影响，对工程的设计和施工具有一定的指导意义。 |

| In recent years, with the large scale construction of China’s railway transport, a growing number of new railways are being built with tunnels under passing existing railways and are producing increasingly serious impact. In this paper, by means of finite element numerical simulation method, the deformation law of roadbed and rail structure of the existing railways are studied when the under passing tunnel is built, obtaining the deformation of the existing line, which has certain guiding significance for the design and construction of similar projects. |
