摘　　要：针对地铁土层的冻结黏土进行冻胀和温度等方面进行试验分析,从而获得冻胀和温度随时间的变化的一般规律。研究表明,能够为地铁中冻结法隧道凿井提供更为有效可靠的依据和便利,从而更为体现其优越性。In this paper, the frost heave and temperature of the frozen clay in subway soil layer are tested and analyzed, so as to obtain the general law of the frost heave and temperature change with time. The research shows that it can provide a more effective and reliable basis and convenience for the freezing method tunnel drilling in the subway, so as to better reflect its advantages.
