Other Abstract采用一维垂直积水入渗法,分析聚丙烯酸钠在4种质量分数(0、0.08%、0.20%与0.50%)处理下对砂土、壤土和黏土水分入渗性能以及Kostiakov入渗模型参数的影响。结果表明:聚丙烯酸钠与土壤质量比在0.08%~0.50%范围内时,3种土壤质地入渗速率都随时间推移呈下降趋势,土壤入渗能力随聚丙烯酸钠质量分数的增大明显降低;聚丙烯酸钠显著抑制土壤入渗能力;入渗系数k随聚丙烯酸钠用量的增加而下降;入渗指数a值随聚丙烯酸钠用量的增加基本呈上升趋势;k/a值对聚丙烯酸钠的响应随聚丙烯酸钠质量分数的增加逐渐增强。; Based on the experiment of one-dimensional vertical infiltration in laboratory conditions,the effect of Sodium Polyacrylate on infiltration capacity of sandy, loamy,and clayey soil and infiltration parameters of Kostiakov infiltration equations were studied.Four concentrations of sodium polyacrylate(0,0.08%,0.20%,and 0.50%),on dry weight basis,were added to these three soils.The results show that the concentration of sodium polyacrylate is controlled from 0.08% to 0.50% by weight,then the infiltration rate ...
