Abstract

The in situ observation of the ground temperature was conducted in the embankment of Qinghai-Tibetan Railway on the Beiluhe field site. The results suggest that the mean annual ground temperature in the depth of 0.5 m on south side is 3 °C higher than that on the north side. The difference becomes prominent in winter time and less in warmer season, which is because the south side of the embankment slope faces to the sun and can receive more solar energy while the north lies back to the sun and receive less. However, the thermal difference on the two sides may result in an asymmetric thermal field in the embankment and even in the foundation soil. So the possible un-even traverse settlement should be concerned for the trail stability.
