Consolidation time
How Cv relates to the profile. The time estimate uses Terzaghi one-dimensional consolidation, t = Tv Hdr2 / Cv. Hdr is taken from the sum of every layer marked as clay (2 m: L1 (2 m)). The Cv you enter is a single representative value for that lumped compressible thickness—it is not read automatically from layer rows. With several clay layers of different properties, this is only a coarse screen: choose a thickness-weighted average Cv, a conservative (slow) Cv, or use layered / numerical consolidation analysis for design.
Target U = 90%, Tv = 0.8480, Hdr = 1.000 m, Cv = 1.2000 m²/year.
Estimated completion time = 0.707 years (257.9 days)
