摘要
通过对粉土路基的特点及水损害进行分析,引入SCP除湿剂,与水泥、生石灰改良粉土室内试验进行对比,研究改良后粉土的物理性质指标、颗粒组成、强度及水稳定性的变化。试验结果表明:SCP除湿剂可用作粉土路基改良剂,可较好地改善粉土的物理性质,提高粉土的强度和水稳定性。该研究成果为既有线路基改良技术提供了试验依据和建议。
The characteristics and water damage of silt sand subgrade are analyzed,SCP desiccant is introduced,the improvement of silt sand test is contrasted with cement and quicklime.The index of physical property,particle composition,the strength and stability of water change after the improvements.All the results show that SCP desiccant used as silt sand subgrade conditioner,can improve the physical properties of the silt,the strength and the water stability,which can be provided for the improvement of the technology of the existing railway subgrade.
