| 摘 要： | 论文基于田间坡地人工模拟降雨实验,分析了料浆石覆盖及嵌入对入渗过程的影响,对比了其入渗速率及拟合参数的变化趋势。其结果表明,随料浆石覆盖度及料浆石嵌入含量的增加,入渗补给系数逐渐减小,且后者对其影响显著;料浆石嵌入小区的平均入渗速率及稳定入渗速率随料浆石含量的增加而缓慢减小。Kostiakov入渗经验公式和Philip方程均可以对降雨入渗过程进行描述。 |

| Abstract: | Based on the artificial rainfall experiment on the slope land,the effects of calcium nodule content(embedded in soil) and coverage on infiltration process were studied,as well as the infiltration rate and fitting parameters.The results showed that both of the calcium nodule content and coverage had obvious effects on recharge coefficient,while the effect of the former was much more obvious.The average infiltration rate and the stable infiltration rate decreased with the increase of calcium nodule content.Bo... |
