摘　　要：随着城市地下空间建设的快速发展,盾构法隧道穿越铁路工程的工况越来越多。如何在保证铁路正常运营的条件下,控制盾构穿越施工引起的铁路路基沉降变形是重中之重。结合轨道交通工程,采用有限元软件,介绍和分析了盾构机下穿、侧穿施工对铁路的影响,并提出适应性施工措施。With the rapid development of urban underground space construction,there are more and more shield tunnel projects passing through railways.It is most important to control the settlement and deformation of railway roadbed caused by shield machine tunneling through the railway under the normal operation.Combined with the rail transit project,the impact of shield machine tunneling underneath or side passing through a railway is introduced and analyzed by the finite element software,and adaptive construction measures are proposed.
