| 中文摘要: |
| 路基土的耐干湿循环特性反映了其抵抗自然环境中水分变化产生破坏的能力，是路基填土耐久性最重要的指标之一。结合室内试验研究了低液限粉土及其改良土（水泥改良土和石灰改良土）在不同的干湿循环次数条件下的工程特性，分析了干湿循环次数对土体抗压强度及其变形的影响规律，提出了低液限粉土宜于水泥改良的结论，为工程应用提供了技术参考。 |
| 英文摘要: |
| The engineering property of subgrade material under wetting drying cycle is one of the most important indexes. In this paper, the engineering properties of low liquid limit silt, cement improved soil and lime-improved soil are studied under different wetting drying cycle in the indoor test. The influence rule of wetting drying cycle on the compressive strength and deformation of soil mass are analyzed. Better engineering properties of cement-improved low liquid limit silt are obtained. |
