摘　　要：针对青藏铁路运营以来多年冻土区出现的路基病害的类型划分、形成原因及主控因素进行分析研究,提出青藏铁路多年冻土区桥头路基存在的病害问题、主要影响因素及桥头路基病害治理工程措施,并对多年冻土区路基工程热稳定性变化趋势进行预测。Focusing on the subgrade defects in the permafrost region since the Qinghai-Tibet Railway had been put into operation, the thesis analyzed and researched the classification, the reasons and the main control factors about these subgrade defects. And then, after analyzing the main influence factors on these subgrade defects which occurred at the bridgehead in the permafrost region along Qinghai-Tibet Railway, the thesis put forward the engineering measures for the treatment of these defects. In addition, a forecast for the variation tendency of thermal stability of subgrade engineering in the permafrost regions was carried out.
