文章对哈尔滨地区的粉质粘土进行了冻结过程的水分迁移试验,考察了含水率、冻结温度及干密度在封闭系统的条件下对粉质粘土中水分迁移的影响。结果表明,控制含水率和干密度相同,顶板的冻结温度越高,水分迁移量越大,顶板冻结温度为-3℃的水分迁移量较冻结温度为-9℃的水分迁移量大;控制顶板冻结温度和干密度相同,初始含水率大的试样,水分迁移量大;控制顶板冻结温度和含水率相同,水分迁移量随干密度的增加而减小。
文章對哈爾濱地區的粉質粘土進行瞭凍結過程的水分遷移試驗,攷察瞭含水率、凍結溫度及榦密度在封閉繫統的條件下對粉質粘土中水分遷移的影響。結果錶明,控製含水率和榦密度相同,頂闆的凍結溫度越高,水分遷移量越大,頂闆凍結溫度為-3℃的水分遷移量較凍結溫度為-9℃的水分遷移量大;控製頂闆凍結溫度和榦密度相同,初始含水率大的試樣,水分遷移量大;控製頂闆凍結溫度和含水率相同,水分遷移量隨榦密度的增加而減小。

Aiming at the silty clay in Harbin, the moisture transfer of the freezing process is tested. We study the impacts of the moisture content, freezing temperatures and dry density on the moisture transfer of silty clay in the closed system. The results show that the higher the top board temperature is, the bigger water migration is, when moisture content and dry density of the test case keep unchanged. The moisture transfer of the top board temperature at-3℃is higher than that at-9℃. when the top board temperature and dry density of the test case keep unchanged, the more the initial moisture content of the soil samples is, the more the water migration is. When the top board temperature and moisture content of the test case keep unchanged, the moisture transfer wanes with the increment of dry density.
