在分析冻胀形成原因的基础上，提出了一维条件下土体冻胀量计算的一种算法；该算法考虑了水分迁移、热传导和约束压力之间的耦合作用．根据实测数据进行计算所得结果与现场实测结果吻合较好．
Based on the analysis of the causes of frost heave, an algorithm is proposed to calculate the amount of soil frost heaving under one-dimensional conditions. The algorithm considers the coupling between moisture migration, heat conduction and restraint pressure. The calculated results based on the measured data are in good agreement with the actual field measurements.
