入渗是水文学中重要的基本概念,定量确定土壤入渗性能对认识水循环及水利用具有重要的理论意义和实践价值。该文建立了用于水利专业本科生教学的土壤入渗测定装置,该装置包括人工降雨装置与土壤入渗装置,可进行降雨的人工控制、入渗量测量和土壤水分测量。测试结果表明,该装置能够较好地反映土壤入渗过程,可以得到比较可靠的实验数据。
Infiltration is an important basic concept in hydrology. Quantitative determination of soil infiltration performance has important theoretical and practical value for understanding water cycle and water utilization. This paper established soil infiltration measuring device for undergraduate teaching of water conservancy, which includes artificial rainfall device and soil infiltration device, which can be used for rainfall control, infiltration measurement and soil moisture measurement. The test results show that the device can better reflect the soil infiltration process, can get more reliable experimental data.
