摘要
通过调节试验箱顶板、底板和箱体的温度模式,在正冻和正融试验条件下对粉质粘土的水分迁移进行试验研究。共做了四组试验,每组两个试样,一个用于冻结后测含水量,另一个用于测融化到设定位置的含水量。在其他试验条件相同的条件下,改变初始含水量或温度模式,研究了单个因素对水分迁移的影响。
Through adjusting the temperature mode of top plate, bottom plate and box body, this paper carried out the research on the water migration of manipulated soil under different freezing and thawing test engineering- conditions. The samples are divided into four groups, two samples had been tested, one were used in freezing test and the others are used in thawing to setting position. In order to research the effect of one type of condition on water migration, the test conditions of initial water content and temperature were changed respectively, and keep the other test condition constant. The results showed that the higher is the water content and the lower is the temperature of top plate, the larger amount of water migrates.
