遼西低山丘陵區(qū)坡地礫石含量及粒徑對(duì)土壤入滲性能的影響
[Abstract]:Based on the laboratory soil column simulation test, the soil infiltration law of different particle size and gravel content in sloping land of low mountain and hilly region in western Liaoning Province was analyzed, and the applicability of gravel soil to the traditional soil infiltration model was analyzed by using four kinds of models. The results showed that the soil cumulative infiltration decreased with the increase of gravel content, the change rate of soil column wetting front changed from small to large with the increase of cumulative infiltration amount, and when gravel content was less than 20, the wetting front advanced to a certain depth. The cumulative infiltration of soil increased with the increase of particle size, and when the gravel content increased to a certain value, there was no difference between the cumulative infiltration amount of soil and the wetting front with the same diameter of gravel content. There is a good linear relationship between the cumulative infiltration and the propulsive distance of the wetting front. Green-Ampt model, general model Horton model and Kostiakov model were used to fit the relationship between infiltration rate and infiltration duration. The fitting effect of Horton model is the worst when the gravel content is 10 ~ 30. The fitting effect of other models varies with gravel content and particle size.
