Abstract:: In order to explore the effect of gasification slag on the aeolian sandy soil of the Mu Us Desert, the effects of mixture of the aeolian sand soil with different amounts of the gasification slag used as a kind of aeolian sand soil improvement material on the soil moisture physical properties of aeolian sandy soil were examined through analyzing of the changes in the particle size composition, water retention performance and moisture characteristic curve of the aeolian sand soil mixed with the gasification slag. The results show that the addition of gasification slag can significantly improve the particle size composition of the aeolian sandy soil; the sand content is reduced by 5.89%～35.8%, and the content of clay and silt particles are increased by 0.89%～2.92% and 7.94%～32.88%, respectively, which the aeolian sand soil bulk density significantly reduces(p<0.05), the decrease range is 7.75%～55.5%; the soil texture of aeolian sandy soil has also changed from sandy soil to sandy loam, and the water retention performance also shows an upward trend, which significantly affects the saturated water content of the soil and the capillary water holding capacity and field water holding capacity(p<0.05), the increase rates are 13.53%～158.93%, 7.12%～126.95%, 23.19%～252.47%, respectively; Van Genuchten model can well fit the aeolian sandy soil after adding gasification slag; the soil moisture characteristic curve shows that the addition of gasification slag significantly improves soil water retention, and the principal component analysis results of the soil water retention performance of aeolian sandy soil indicate that the higher the addition of gasification slag is, the more obvious the improvement of soil water retention is. It can be concluded that the coal water slurry gasification slag can effectively improve the water physical properties of the aeolian sandy soil, significantly improve the water retention performance of the aeolian sandy soil, and have a significant effect on the improvement of the aeolian sandy soil.
