本文根据甘肃省1979年以来的渠道冻胀试验成果,得出了4种冻胀沿深度分布的类型及其与地下水位和土质条件的关系。其分布规律可用水分迁移理论加以解释。所谓“主冻胀层”概念仅适用于封闭冻结系统。根据一个简化的水热迁移模型计算也证实了地下水热影响。
Based on the results of the channel frost heaving test in Gansu Province since 1979, the types of the distribution of the four frost heave along depths and their relationship with the groundwater level and soil conditions were obtained. The distribution law can be explained by the theory of moisture migration. The so-called “main frost heave layer” concept applies only to closed freeze systems. Calculations based on a simplified hydrothermal migration model also confirmed the thermal effects of groundwater.
