南水北调中线工程河北省磁县段广泛分布的上第三系中新统( N1)地层中大部分黏土岩具有膨胀性，强、中、弱、非膨胀岩(土)交错分布，可与其他地区膨胀岩(土)进行对比研究。通过野外鉴别与室内试验数据判别，对研究区膨胀岩(土)各指标之间的相关关系进行分析，总结了从颜色、结构构造、裂隙发育特点等宏观工程地质特征，得出了膨胀岩(土)膨胀等级的野外快速鉴别方法。研究结果对工程处理方法选择、施工开挖、野外施工地质工作都有积极意义。

In the Middle Route of South to North Water Transfer Project in Cicounty of Hebei,most of the wide spread clay rock of the Neogene system Miocene series stratum shows swelling characteristics. Strong, medium, weak, and nonswelling rock ( soil) is in interlaced distribution, which can be compared with the swelling rock ( soil) in other areas. Based on the identification of field and laboratory data,the relationship between each index of the swelling rock (soil) was analyzed. The rapid field identification method of the grade of swelling rock (soil) was obtained from the engineering geological characteristics such as color, structure,and fracture development. The research result is of important significance to the selection of engineering method, excavation , and field geology.
