摘要
为了研究湖南广泛分布且天然含水量较大的高液限红粘土的非饱和性质,以便有利于指导高速公路路基填筑及边坡防护的施工设计。本文主要通过非饱和土试验研究了红粘土的土-水特征曲线(SWCC)及非饱和土的力学土性参数,且分析了土的粒径对土水特征曲线的影响及不同吸力下红粘土的强度变化情况。
The red clay distributed widely in the HuNan province,which is of high natural moisture and high limit.The unsaturated soil property of the red soil such as SWCC of red soil and the earth parameter was studied by trial,meanwhile,the grain size of the soil impacted on the SWCC and the suction impacted on the strength of the red soil were analyzed respectively.The result can be used to direct the fill of roadbed and the design of slope protection.
