    Numerical analysis of preventing measures of roadbed problems in the permafrost regions of Yaling Railway

      摘要
    • 摘要: 既有东北铁路多年冻土区路基病害严重,为保证既有铁路的正常运营,综合运用多种防治措施进行了路基病害整治的试验研究。牙林线北段试验工程含274K500m~275K000m、275K460~276K000m两个路基试验段,该试验工程综合运用了XPS保温板、EPS保温板、热棒、保温护道等积极有效的防治措施。本文针对牙林线北段试验工程段,结合现场实测地质资料和气温资料,利用有限元分析软件对该试验段路基病害整治效果进行了数值分析研究。

       

      Abstract: The roadbed problems are very serious in the permafrost regions in Northeast China.And manifold preventing measures are applied in experiment engineering to solve the roadbed problems.There are two sections(274K500～275K000m、275K460～276K000m) in experiment engineering in the north region of Yaling Railway.And some active preventing measures such as insulated materials(XPS、EPS) and two-phase closed thermosyphon are applied in these two sections.Based on the data of temperature and geology in the region,the effectiveness of these measures is studied by numerical analysis method in this paper.
