摘　　要：土料的分散性是决定土料能否用于工程的重要因素,通过针孔、孔隙水可溶盐和交换性钠百分比、土块、双比重计等4种试验方法,综合土样物理化学性质和黏土矿物成份分析,对金沟河红山水库筑坝土料存在的分散性黏土进行分析并确定其类型。Soil material dispersion is an important factor to determine whether the soil material to be used in the project ,with four kinds of double hydrometer test methods, through the pinhole soluble, pore water soluble salt,exchangeable sodium percentage,soil samples,it complexes physical and chemical properties and clay mineral composition analysis ;Jingouhe Hongshan Reservoir dam soil dispersion was analyzed and clay type was determined.
