摘要
盐渍土对公路造成的危害严重、经济损失巨大,为了更好地控制土壤盐渍化,解决各类建筑工程中的盐胀病害,因此在公路建设中应加强对这个方面防治研究、实施合理措施,拟进行盐渍土击实试验研究,试验是在土中掺入不同含量的硫酸钠、氯化钠、碳酸钠,得到各种含盐量的最大干重度和最佳含水量,能有效地提供现场施工质量控制方法,从而为提出更为有效的盐胀治理措施提供理论依据。
Salty soil is very harmful to highway construction work and also causes high economic loses. To prevent the adverse effect of salty soil on highway construction work, this paper experiments on compaction of salty soil with different proportion of sodium sulfate, sodium chloride and sodium carbonate, and found the driest density and the best moisture content values, thus the author is able to provide an effective method to control construction quality. The study reveals the relation between moisture and salinity of salty soil and provides an effective theory basis for managing measures against the expansion of salty soil.
