| 摘 要： | 选取典型细粒硫酸盐渍土,进行反复冻融循环条件下的试验研究,分析了典型细粒硫酸盐渍土的盐胀规律。试验结果表明:低液限黏土硫酸盐渍土的前5次冻融循环过程中盐胀具有较好累加性,随着冻融循环次数的增加,盐胀量增长速度逐渐降低;含砂低液限黏土硫酸盐渍土的盐胀过程可以被分为3个阶段。

| Abstract: | The representative crude saline soil samples were selected for the experiment of freezing and thawing cycles in our laboratory.The salt expansion laws of saline soil were researched from two kinds of soil.The test result showed that salt expansion value of low liquid-limit clay is accumulated before the sixth freezing and thawing cycles,but the increment of salt expansion is reduced gradually with increasing times of freezing and thawing cycles;the salt expansion with low liquid-limit clay can be separated ... |
