Abstract:The soil infiltration characteristic is one of the most important soil physical properties. The structure and texture of the soil configuration in Shanxi-Shaanxi-Inner Mongolia energy zone are quite complex which results in different infiltration properties. The infiltration characteristics of different soil configurations were analyzed by one-dimensional vertical infiltration experiment. The results showed that soil infiltration characteristics were strongly influenced by soil configuration, and the infiltration capacity was decreased in the order of aeolian sandy soil, loess soil and soft rock. The mixed and layered addition of soft rock to aeolian sandy soil and loess soil both could extend infiltration time and reduce infiltration rate. The infiltration process of soil containing calcites and gangue was inhibited under the high bulk density condition. Layered structure soil had a lower infiltration capacity than that of homogeneous soil. The relationship between cumulative infiltration and wetting front advancing distance could be well expressed as a linear function model. Kostiakov infiltration model could better fit the infiltration process with different configurations (R2>093) than that of Philip model. The results provided an experimental evidence for soil water movement process and also offered a technical support for the reconstruction and reclamation of mining soils in Shanxi-Shaanxi-Inner Mongolia energy zone.
