英文摘要	The Harbin-Dalian Passenger Dedicated Line (HDPDL) was the first high-speed railway in typical middle-deep seasonally frozen regions in Northeast China. One typical feature of the HDPDL was that the subgrade length (231.245 km) accounted for 25.58% of the total railway length (904 km). Considering the condition of transition sections between subgrade and bridge, culvert and tunnel, thermal regime under them would severely restrict the subgrade stability and irregularity in winter. So, an auto-monitoring system has been set up at several typical cross-sections along the HDPDL. The analysis results indicated that in the first freezing-thawing period after operation, the maximum frozen depth (MFD) under the subgrade shoulder increased as latitude increased, and that the time of reaching the maximum frozen depth showed a similar trend. But the amount of frost heaving of subgrade shoulder showed a different pattern. The ground temperature and deformation characteristics were significantly different under the subgrade structure styles and the sunny-shady slope effects. At last, based on a long-term estimation, that applied the amount of frost heaving needs more carefully. (C) 2015 Elsevier B.V. All rights reserved.
