| Abstract: | Harbin-Dalian Passenger dedicated line locates in permafrost regions. It is influenced by such factors as the temperature, and subgrade deformation is easy to occur there. Based on field investigation, three typical cross sections along the line were selected and monitored for settlement deformation, earth temperature, soil stress, moisture content in a cycle of freezing and thawing period. The monitoring and analyzing results are consistent with the actual engineering, providing the basis for subgrade stability evaluation and important reference to projects. |

| Keywords: | cold regions passenger dedicated line subgrade deformation monitoring earth temperature moisture content soil stress settlement |
