关于孔隙应力比如何确定的？

对于Geoslope软件计算中关于孔隙应力比ru如何确定的？
土工原理与计算教材中说对于某土坡，ru已经确定，是如何计算的？画了水位线，还要计算这个值？

Ru Coefficients An ru value must be specified for each soil type.  
The ru coefficient is defined as:
ru=u/γhi，


where:

γ the total unit weight of each soil strata in the slice

hi = the average thickness of each soil strata in the slice

i = the soil strata number

u = pore-water pressure
