摘　　要：新疆南疆属盐渍土分布较广、盐渍土灾害严重的内陆干旱荒漠区域。不同地区由于地形、地貌及地下水分布的差异,导致其盐渍土工程性质有着明显的区别,使盐渍土灾害防治存在不确定因素。作者通过南疆三地区盐渍土工程性质的试验对比研究,试验分析结果表明:南疆不同地区受区域地形、地貌及地下水分布的差异和地质构造的影响,其盐渍土分布具有较明显的区域分异性,盐分组成及含盐量具有很大的差异,使不同地区的盐渍土在力学强度、土的可塑性及盐渍土盐-冻胀变形特性方面存在较大的差异。Southern Xinjiang is inland arid desert region, it is wider distribution of saline soil and saline soil disasters. Because of topography, geomorphology and groundwater distribution differences in different areas of Southern Xinjiang, there was a clear distinction in saline soil engineering properties, so that saline soil in disaster prevention exist uncertainties. Through test study saline soil engineering properties of three regions in Southern Xinjiang, Results showed that： different regions of Southern Xinjiang by the regional topography, geomorphology and groundwater distribution of differences and the effects of geological structure. It has a very different by the distribution of saline soil with more pronounced regional differences in salt composition and salt eontenl. This difference so that sa- line soil in the mechanical strength and plasticity of soil and saline soil salt - frost heave deformation characteristics exist greater differences.
