Characteristics and dynamic changes of soil water infiltration under different soil bulk density and different stabilizer content were analyzed by one-dimensional vertical infiltration experiments. The results showed that soil bulk density had significant influences on infiltration capacity of stabilized soil from 1.2～1.4g/cm3 of soil bulk density ranged. The influences of soil bulk density on infiltration rate were stable and constituent. With increasing soil bulk density, cumulative infiltration decreased. Stabilizer amendment amount had effects on cumulative infiltration and wetting front under the same soil bulk density. Cumulative infiltration were the highest at 0.05%～0.1% amendment amount of EN—1 stabilizer, and were higher the control. There was good linear relationship between the amount of cumulative infiltration and the wetting front distance. With increasing amendment amount of EN—1 stabilizer, cumulative infiltration and wetting front had trend of increase first and decrease then. Fitting the relationship between infiltration rate and time with Philip model, Kostiakov empirical formula and index formula, the results showed Kostiakov formula was more accurate than other models and fitted values of its had the best results at higher soil bulk density.
