| 摘 要： | 根据青藏高原东部地区高温多年冻土地段的自然地理及地质水文条件,利用部分试验路段的实测资料,对该区在分别修建不同高度的沥青、水泥混凝土、砂砾路面后路基的热稳定性进行了模拟分析,根据计算结果就不同路面类型在该区高温冻土地段的适用性进行了探讨。

| Abstract: | The heat stability of embankment in the high temperature permafrost regions of the eastern Tibetan Plateau was simulated,and the heights of embankment were discussed and figured out,respectively for asphalt-paved,concrete and gravel road surface,according to the natural geographic and geologic conditions in the high temperature permafrost regions of the district.The calculated results were in good agreement with the field data of the Qinghai-Xizang Highway. |

| Keywords: | high temperature permafrost heat stability of embankment natural permafrost table critical height of embankment unfrozen core |
