Abstract: Due to less of covered soil afer fllig subsided land with Yellow River sediment layer,alternative soils,which was mixed by topsoil, subsoil and Yellow Riv er sediment,was proposed to solve this problem.In this study,one-dimensional vertical infiltration of alternative soils was researched.The results showed that initial and stable infiltrative rate of alternative soils both increased with sediment content in alternative soils,ranging from 0.461 5 to 4.166 7 cm/min,0.032 9 to 0.327 3 cm/min,res pectively.The relationship between initial and stable infiltrative rate and sediment content had dramatic positive correlation and extremely positive correlation,respectivel y.The cumulative infiltration and wetting front depth also increased with sediment contents,under the same infiltration time,moisture could enter soil rapidly,which was C onducive to decrease surface runoff.In addition,the Kostiakov model used to fit the relationship of infiltration and time,and it got a very well result.The alternative soils W ith ratio of topsoil,subsoil and sediment were 1 : 1 :0.86,1 :1 : 1.33,1 : 1 : 2,their texture were loam,the infiltration effect was better or approach cultivated land,and wat er holding capacity was good.With principle of the more covered soil the better,we recommended that 1 : 1 : 2 was the suitable ratio of topsoil,subsoil and sediment of al ternative soil,and it could be used as alternative materials to cover on Yellow River sediment layer in mining subsided land flling and reclamation.
