摘　　要：为了揭示改良剂对盐渍土的力学性质的影响机理,利用扫描电子显微镜(SEM)对改良盐渍土的微观结构进行了分析,探讨了不同改良剂、不同剂量对改良土的微观结构的影响。研究结果表明:改良盐渍土在添加改良剂前后,微观结构特征明显不同,添加改良剂有效的改善了盐渍土的稳定性和强度,从而从微观结构揭示了改良剂对盐渍土力学性质的影响机理。in order to reveal the mechanical properties of saline soil,the author of the paper analyzed the improvement of saline soil micro-structure through scanning electron microscopy.The different modifiers and different does of an improved micro-structure of soil are discussed in the paper.The results shows,the micro-structure of improve saline soil is obviously different before and after improvers is added.The improvers of types and does chosen in this topic can effectively Improver the stability and strength of saline soil,and then reveal the mechanical properties of saline soil from the aspect of micros-structure.
