摘　　要：选用枣临铁路DK5＋160-DK5＋400穿越采空区路段的工程实例,应用MIDAS/GTS数值软件对不同工况条件下的铁路-采空区模型进行三维数值模拟,将采空区地表沉降值进行对比分析,从而对铁路路基的稳定性进行评价并提出合理的建议。Zaolin railway DK5 ＋ 160 - DK5 ＋ 400 through the mined-out area was selected as an engineering example in this article,and the MIDAS /GTS numerical software was applied for 3D numerical simulation of railway-goaf area under different working conditions.The goaf area sedimentation values were analyzed,and the railway roadbed stability was evaluated and reasonable suggestions were put forward.
