摘要
在工程地质勘察、土样微观分析以及大量试验的基础上，对３２２国道南宁段膨胀土的成因及物质成分进行了较全面的分析，着重研究了膨胀土的工程性质及其对路基稳定性影响，为有效地进行该路段路基稳定性设计提供了依据。
On the basis of engineering geological exploration, analysis of material composition at microscopic and a lot of soil textings, the origin and the material composition of the expansive soil occuring in Nanning section of National highway No. 322 are analysed in this paper, the engineering properties of the expansive soil and the effect of expansive soil for subgrade stability are studied mainly, therefore, an effective basis for the design of subgrade stability in this road section are presented.
