围绕季节性冻土地区高速铁路无砟轨道路基冻胀预防问题，简述了无砟轨道的特性及冻害对无砟轨道的影响。分析了气候环境、地形条件、冻结深度、填料类别及含水率、水、积雪、路基类型、路堤高度等使路基产生冻胀的因素，并重点对线路选线、标准冻结深度综合修正、路基面高程、抗冻填料等进行了论述，提出了有待试验研究的问题。
圍繞季節性凍土地區高速鐵路無砟軌道路基凍脹預防問題，簡述瞭無砟軌道的特性及凍害對無砟軌道的影響。分析瞭氣候環境、地形條件、凍結深度、填料類彆及含水率、水、積雪、路基類型、路隄高度等使路基產生凍脹的因素，併重點對線路選線、標準凍結深度綜閤脩正、路基麵高程、抗凍填料等進行瞭論述，提齣瞭有待試驗研究的問題。

T he paper outlines the general features of ballastless track and its reaction to frost hazard. Possible reasons behind,including climate,environment,geological conditions,depth of freezing,type of filling,moisture content, subgrade structure and embankment height are studied. Alongside that,it studies issues like line selection,correction of freezing depth,elevation of subgrade surface and anti-frost filling,so as to underline the key topics in experimental study. All in all,the paper intends to conclude favorable solutions to the frost heaving problems ballastless track suffers in areas with seasonal frozen soil and lay out ground for future study.
