摘　　要：文章以广西钦州至崇左高速公路上思境内典型膨胀土路段堑坡工程为例,通过基本物理力学性质试验和胀缩性试验,对膨胀岩土的工程特性进行了深入研究。结果表明,该区段膨胀岩土具有含水率低、孔隙比小、质量干密度大、液塑限高、压缩性低、抗剪强度高及胀缩潜势强等特性。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.
