Is this necessary to deduct [b]Always the pore water water pressure (u) from saturated soils while solving numerical problems? What is the Principal Rule to be applied on deducting Pore water Pressure?

Please review basic geotechnical texts such as Craig or Conduto.
As an example, you would NOT deduct the pore water pressures (phreatic surface head) when determining the driving forces of a slice in a slope stability problem but you would when you are determining the resisting forces. For consolidation testing (i.e., settlement computations) you would use the effective unit weights.
