摘要
为了研究盐渍土低液限粘土在冻融循环条件下水盐迁移的变化,通过室内模拟实验,对低液限粘土进行含水量和易溶盐含量进行测试分析。研究表明,盐渍土的水分和盐分迁移总体上是由试样下部向冷端迁移,但沿试样高度的迁移呈称非线性,局部出现随机波动的特点。
In order to research the migration laws of water and salt on Saline oil under the condition of cycle of freezing and thawing, the water content and contentof easysolublesah were tested andanalysed through labsimulation test. Results show that the water and salt migrated from the top of the samples to thecoldend generally, themi- grationamount was nonlinearrelationalong thesectionheightofsamples, locallypresent of samples took on casualfluctuation.
