| 摘 要： | 青藏铁路斜坡段路基是铁路长期运营潜在的不安全隐患,评价现今和未来斜坡路基稳定性能为铁路安全通行提供保证。多年冻土斜坡路基稳定性分析不同于普通土路基,冻融交界面位置是斜坡路基稳定性重要影响因素。本文通过监测安多试验段的变形特征,详细分析了各个地段路基的变形规律,建立了斜坡路基稳定性评价模型。

| Abstract: | There is an incipient fault to long-period operation in the sector of embankment upon the slope, so it is important for long-time safety traffic to evaluate the inclined embankment of recent or future time. Stability assessment of railway slope roadbed in permafrost area is difficult from others, because the location of interface between frosting and thawing is an allimportant factor to the stability of the embankment. Though monitoring the features of temperature and displacement of embankment in the paper, the deformation laws of each section are analyzed in details and the appraisal models are built. |
