| 摘 要： | 冻结温度是判别土体是否处于冻结状态的指标,在人工冻结和数值模拟计算中影响冻结壁的厚度和计算精度.通过采用不同土体添加不同的盐分,对不同含水量和含盐量土体进行盐渍土的冻结温度试验,考虑了不同因素对土体冻结温度的影响.实验表明：不论何种土含有何种离子,土体的冻结温度随含盐量的增加而降低,随含水量的增加而增大;土中易溶盐的含...

| Abstract: | In this paper,the result of an experimental study on the freezing point of saline soil is presented.This study is a part of a larger experiment program aiming to understand the influences of salt content,water content and ion property on the freezing points of various soils.The experimental results show that the freezing point decreases with increasing salt content and increases with increasing water content of various soils.And the freezing point is controlled by the amount of soluble salt in the soil.The ... |
