摘要
通过分析在汾河南内环桥至南中环桥河道段进行的双环垂直入渗试验和颗粒分析试验,探讨了该河段的土壤稳定入渗速率和土壤颗粒组成之间的变化规律。研究结果表明:在土壤颗粒组成中,土壤水稳性团聚体质量分数和土壤稳定入渗速率的相关性最大。试验结果对于确定二期工程防渗措施设计和工程完成后管理运行有实际的应用价值。
This paper discusses variation law between soil steady infiltration ratio and soil granulometric composition in the reach from Fenhe South Inner Ring Bridge to South Intermediate Ring Bridge, through analyzing two-ring vertical infiltration experiment and granulometric composition experiment. The conclusion is that the most relativity with soil steady infiltration ratio is weight percent of soil water-stable aggregate in soil granulometric composition. The results have actual application values in second-stage project and management and running after project being completed.
