计算哈大高速铁路高填土路堤试验段在实际工况下冻胀、融沉过程中温度场的发展趋势。

At the same time the development trend of the temperature field in the process of frost heaving and thaw in the actual condition is calculated .

⑶将数值计算的稳态温度场结果作为初始条件加到路堤计算模型中，实现了温度场与应力场的耦合，采用强度折减法研究融沉期哈大高速铁路试验段高填土路堤的边坡稳定性。

⑶ The coupling between temperature field and stress field is realized through adding steady-state temperature field data to the calculation model of embankment structure as an initial condition . Strength reduction method is adopted to study the slope stability of the embankment in thaw period .

哈大电气化铁路是我国第一条从德国引进的牵引供电技术，它和其它电气化铁路供电系统具有很多特殊性。一是其采用220kV两相供电系统，这在我国还是首次。
