摘　　要：为了探讨水泥剂量、压实系数及浸水时长对改良后盐渍土浸水稳定性的影响,文章分析了不同水泥添加量(0%,3%,5%,7%,10%)和压实系数(92%,95%,98%)下盐渍土的无侧限抗压强度、浸水稳定性以及渗透性,研究结果表明:水泥添加量和压实系数的增加显著提高了盐渍土的抗压强度和浸水稳定性,减少了质量损失率,提升了残留强度比,特别是当水泥添加量达到7%及以上,以及压实系数为98%时,盐渍土具有良好的浸水稳定性。In order to investigate the effects of cement dosage,compaction coefficient and soaking time on the soaking stability of improved saline soil,the unconfined compressive strength,soaking stability and permeability of saline soil under different cement additions(0%,3%,5%,7%,10%)and compaction coefficients(92%,95%,98%)were analyzed.The results show that the increase of cement addition and compaction coefficient significantly improves the compressive strength and soaking stability of saline soil,reduces the mass loss rate and improves the residual strength ratio,especially when the cement addition reaches 7% or more and the compaction coefficient is 98%.Saline soil has good immersion stability.
