ABSTRACT

During the freezing process, water migration is a decisive factor for the estimation of frost heave and thaw-settlements of fine and mixed-grain soils. One-dimensional freezing tests with and without a water supply were carried out. The influence of different temperature gradients of a saturated clay on parameters such as water intake, frost heave, and thaw-settlements is discussed here. A new approach is presented to describe the rate of water intake, which consists of three parameters. This study shows that all three parameters were influenced by the temperature gradient. This approach helps predict frost heave and thaw-settlement in cold regions.

冻融过程中温度梯度对黏土水分迁移、冻胀和融沉的影响

摘要

在冻结过程中，水分迁移是估算细粒土和混合粒土冻胀和融沉的决定性因素。进行了有水和无水供应的一维冷冻试验。本文讨论了饱和粘土的不同温度梯度对吸水量、冻胀和融化沉降等参数的影响。提出了一种描述饮水率的新方法，该方法由三个参数组成。这项研究表明，所有三个参数都受到温度梯度的影响。这种方法有助于预测寒冷地区的冻胀和融沉。
