陕西某地重塑黄土渗透系数的试验研究

On experimental research on reshaped loess permeation parameter in some place of Shanxi province

通过陕西某地黄土重塑试样的常水头试验研究,获得了该地重塑黄土样的渗透系数,其值的变化范围为10-6cm/s^10-7cm/s,发现土样渗透系数总体上随土样干密度的增大而减小,同时对不同含水量黄土经不同击实数后的试样在不同渗透压力下渗透系数的变化特征进行了分析。

According to the research on the constant head tests in samples for reshaped loess of some place in Shanxi,the paper obtains the permeability parameter of the reshaped loess sample,which has the changing scope from 10^-6 cm/s to 10^-7 cm/s,and finds the permeability parameter of the sample reduces,as its dry density increases,and analyzes the changing characteristics of the permeability index of the samples in various permeable pressure after compaction on loess with different liquid water content.
