Unformatted text preview: (i.e. Acr'z = AU), it will also be symmetrical. • Therefore, the average percent consolidation (U), and the corresponding time factor (T), at any given time will be the same above and below midheight. • The following initial pore pressure distributions are equivalent as shown: I Case 1a I Case 3 Case 4 J)o. ..{,lt I)''';'' ,.,,,.

(This is why we defined the maximum drainage path = H/N.)...
