摘　　要：利用双比重计、针孔、碎块和孔隙水可溶盐阳离子4种试验方法对南坪水库土样的分散性进行了研究。试验结果表明,土料K1以砂粒为主,K6、K8以粉粒为主;3组土料的钠含量小,可有效降低土料的分散性;这3组土样中K1、K6属于过渡性土,K8属于非分散性土。The dispersity was indentified by four test methods with double-hydrometer test, pore water salts test, pinhole test and crumb test for the Nanping reservoir soil samples. The results showed that the sample K1 was rich in sand grain, K6 and K8 were rich in silt grain. The three samples were lower Na＋ content, witch can effectively drop the dispersity. K1 and K6 were blong to transitional soil, and K8 was belong to non-disoersive soil.
