本文就六种持水模型在各吸力段的拟合度进行了比较,模型lnS=a+bθ+cθ~2+dθ~3的拟合效果最好,而模型S=aθ~(-b)和S=ae~(b4)虽然简单,但拟合效果最差。
In this paper, the fit of six water-holding models in each suction section was compared. The fitting effect of model lnS = a + bθ + cθ ~ 2 + dθ ~ 3 was the best, and the model S = aθ ~ And S = ae ~ (b4) although the simple, but fitting the worst.
