%X 本文基于数值模拟软件Midas GTS，对某基坑的施工进行全过程的模拟，分析其邻近的铁路线路变形特征。通过简要介绍复杂基坑的数值建模过程、施工荷载的施加，对各个施工步骤造成铁路路基的沉降变形与水平变形进行分析，得到既有铁路路基的变形规律，为同类型的涉铁基坑工程的施工提供参考。<br />
Based on the numerical simulation software Midas GTS, this paper simulates the whole process of the construction of a foundation pit, and analyzes the deformation characteristics of the adjacent railway lines. By briefly introducing the numerical modeling process of complex foundation pits and the application of construction loads, the settlement deformation and horizontal deformation of the railway subgrade caused by each construction step are analyzed, and the deformation law of the existing railway subgrade is obtained to provide references for the construction of the project.
