摘要
为研究季节性冻融区地基土水分迁移的规律,对不同初始含水量以及温度梯度作用下的重塑土进行了冻融试验,试验结果表明:随着初始含水量的增加,土样水分迁移更加明显;温度梯度越大,土样冻结速率越大,水分聚集层越靠近暖端。
In order to study the law of soil moisture transfer in the seasonal freezing and thawing area,the freezing and thawing tests were carried out on the reconstituted soil under different initial water content and temperature gradient. The results show that： with the increase of initial water content,soil moisture transfer is more obvious,the greater the temperature gradient,the greater the soil sample freezing rate,more closer the water collection layer approach to the warm port.
