Abstract Temperature distribution in the roadbed and neighboring soil of high-speed railway(HSR) in seasonally frozen regions has significant influence on the stability of roadbed. The temperature distributions at the toe of slope，a short distance away from the road and at different locations in the roadbed were analyzed based on the results of three years monitoring and the atmospheric temperature data at Shuangcheng district from Harbin-Dalian HSR. Formulae of temperature estimation of different locations and depths were established in terms of the temperature amplitudes and average values. A mathematical model of the unsteady phase transition of geothermal field was presented to analyze the temporal and spatial characteristics of temperatures and to predict the trends of variation of geothermal field. Monitored data and calculated results both indicated that the temperature distributions were related to the soil compositions，the thermal coefficients of diffusion，the climate and the locations，etc. The roadbed of HSR of seasonally frozen regions eventually formed a relatively stable layer of seasonal frozen with a stable temperature and asymmetric geothermal field. The difference of geothermal field of shady and sunny slopes at two sides of embankment exists and may lead to the uneven settlements transversely and longitudinally which may affect the stability of roadbed.

Key words： subgrade engineering seasonally frozen region roadbed of high speed railway temperature distribution shady and sunny slopes stability
