摘要
在分析了影响浑水入渗主要因素的基础上,提出了试验方案。根据浑水入渗试验资料,建立了浑水入渗经验公式。结果表明,浑水与清水入渗的差异主要是由浑水中物理性粘粒的存在引起的。浑水中物理性粘粒含量越大,累积入渗量就越小。这一成果对流域降雨产汇流、土壤侵蚀机理研究及浑水灌溉研究与应用具有一定的价值。
The experimental design plans were determined on analyzing main factors to affect infiltration capability of muddy water. The result shows that the reason of muddy water infiltration differing from rinsing is the clay in muddy water. And the more the soil clay index is, the less the accumulation infiltration amount is. Based on the experimental data, a muddy water infiltration law formula was built. The formula is superior to existing formulae, and it can be used in the research of muddy irrigation, rainfall runoff and erosion processes in watershed.
