摘要

摘要: 野外地表的渗透系数是小流域降雨产流和边坡稳定性计算分析必不可少的参数。介绍了新的野外地表渗透系数的测量装置与方法。该装置结合了降雨入渗试验和双环入渗试验装置的优点,实现了斜坡地表的饱和无压入渗测量。试验数据分析方法可以直接获得地表土层的渗透系数。在某山区流域进行了入渗试验并分析获得了土层的渗透系数与吸力。

Abstract: The permeability coefficient of the field surface is the essential parameter for analyzing both the slope stability and the small watershed rainfall yield. A new method and device is described for field measurement of the surface permeability coefficient. The device combines the advantages of a direct rainfall infiltration test and a two-ring infiltration test device to achieve a saturation surface with zero water pressure infiltration measurement of a slope. The permeability of surface soil can be obtained directly by proposed method. Infiltration tests on a mountainous basin are carried out, and the soil permeability and suction are obtained.
