With the cutting slope engineering of typical expansive soil section at Shangsi section of Qinzhou-Chongzuo Expressway as the case,through testing on the basic physical mechanics nature and the expansion/contraction nature,the article conducted the in-depth study on the engineering properties of expansive soil. The result showed that the expansive soil in this section has properties of low moisture content, small void ratio,dry quality, high density, high liquid plastic limit, low compression, high shear strength and strong swelling/ shrinkage potential etc.
