摘要
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.
Reasons for the formation of frost heave are discussed, and a numerical method is explored which calculates frost heave of soil under one\|dimensional condition. Interactions among water flow, heat transform and constrain pressure are considered in this method. The calculating results are compared with the observation results for the field.
