Method for improving frost heaving and thaw collapse of salinized soil
The invention discloses a method for improving frost heaving and thaw collapse of saline soil. According to the method, attapulgite is doped into salinized soil, and the salinized soil is sodium sulfate salinized soil or sodium carbonate salinized soil. The mass percentage of the attapulgite doped in the sodium sulfate salinized soil or the sodium carbonate salinized soil is 1%-5%. The invention further provides application of the attapulgite in improvement of frost heaving and thaw collapse of the sodium sulfate salinized soil or the sodium carbonate salinized soil. The doping of the nano attapulgite can effectively relieve the moisture migration activeness of the salinized soil sample and inhibit the trend of height expansion of a freezing region, and improve and control the salt frost heaving deformation development of the salinized soil, thereby reducing or avoiding natural and engineering disasters induced by the salinized soil in a freezing and thawing environment.
本发明公开了一种改善盐渍土冻胀和融沉的方法。所述方法是向盐渍土中掺入凹凸棒土，所述盐渍土为硫酸钠盐渍土或碳酸钠盐渍土。所述凹凸棒土在硫酸钠盐渍土或碳酸钠盐渍土中掺入的质量百分含量为1％～5％。本发明还提供了凹凸棒土在改善硫酸钠盐渍土或碳酸钠盐渍土冻胀和融沉中现象中的应用。纳米凹凸棒土的掺入可有效缓解盐渍土样水分迁移活跃度并抑制冻结区高度扩大的趋势，改善和控制盐渍土的盐冻胀变形发展，从而减少或避免盐渍土在冻融环境下盐渍土诱发的自然、工程灾害。
