摘要
为了研究冻融循环对木质素改良土微观结构的影响,开展了不同土体(粉土和粉土质砂)的冻融循环试验.对不同冻融循环次数下粉土和粉土质砂等两种素土及木质素改良土进行微观结构分析.结果表明,木质素改良土的抗冻性优于素土.
In order to study the effect of freeze-thaw cycle on microstructure of lignin-improved soil,freeze-thaw cycle tests of different soils(silty soil and silty sand) were carried out.The microstructure of two kinds of soils and lignin improved soils with different freeze-thaw cycles were analyzed.The results showed that the frost resistance of lignin improved soil was better than that of soil.
