摘要 吉林省大安地区分布着大量盐渍土,冬季温度降低后土体发生冻胀会引,会引发一系列工程危害。本文对吉林省大安地区盐渍土体进行野外取样,并进行室内基本物理、化学及物质组成试验,通过室内冻胀试验模拟土体冻胀过程,查明土体冻胀特性。试验结果表明,研究区土体为碳酸盐渍土,钠离子含量较高,交换性阳离子含量较高;土体在冻胀过程中其击实度、含水率及土体中含盐量均不同程度影响着冻胀结果,对于各含盐量下土样均存在最佳击实度;盐分过少时对冻胀产生抑制作用,达到一定含盐量后产生盐胀,对冻胀产生促进作用;研究区起始冻胀含水率为21%。该结论为防治吉林省西部盐渍土地区由冻胀作用带来的工程灾害防治提供理论依据。

Abstract: There are plenty saline soil distributed in Da'an area, Jilin Province. Those soils show frost heave deformation due to the low temperature in winter, which can cause serious damage to construction projects and building structures. This paper takes field sampling collections of saline soil in Da'an area, Jilin Province. The physical and chemical property, soil grain composition of the soil samples are tested. The frost heave properties are studied using indoor frost heaving simulation experiment. The experiment results show that the salinization type of soil samples is carbonic acid type. Soil samples of research area have high exchangeable cation content and sodion content. The water content, salt content and compaction degree of soil samples all show imparity influence to the frost heaving results during frost heaving process. Frost heaving tests are carried out. The results show that with the temperature decreasing the frost heaving ratio increases. Only the frost heaving ration does not change much nearby the-10℃. For most of soil samples, with the compaction degree increasing the frost heaving ratio basically increases. The compaction degree affects frost heaving ration more obviously at low water contents soil samples. The soil samples of high salt content show lager frost heaving ratio than the low salt content samples. Besides, the frost heaving ratio take longer time to be stabilized than the low salt content samples. According to the test results, the largest frost heaving ratio is 3.5%. It ends up at soil samples with 26% water content, 1.5% salt content and 90%compaction degree. There is a best compaction degree of different salt content soil samples. The heaving ratio is increased by compaction degree of low salt content samples. But for high salt content samples, it shows inhibiting effect to soil if the compaction degree is too high or too low. For very low water content samples, high salt content shows inhibiting effect to soil samples. The soil samples show frost heaving only when the salt content is high enough. Soil has a frost heaving beginning water content, the frost heaving beginning water content of Da'an saline soil is 21%. This research provides theoretical basis to preventative mature of frost heaving damage in west Jilin Province.
