摘要：以实际工程地质勘察成果及数据为依据，全面分析了南水北调中线京石段分布的黄土状土的工程地质特征，并作出了评价，评价结论为渠段内黄土大部分不具湿陷性，局部具较弱湿陷性，个别场地具中等湿陷性，对工程影响不大。

Abstract:The article analyzed the engineering geologic characteristics of loess of Beijing to Shijiazhuang segment by the investigated tesults and data and made some conclusion that most of the loess within the segment are not of wet sinking characteristic,the partial places is weaker,few places have medium wet sinking characteristic,which influence to the engineering is not so big.

Key words:loess soil;wet sinking characteristic;evaluation
