Seepage flow for Isotropic Soil, Q correct answers Q = k(delta(H))(Nf/Nd) k - coefficient of permeability delta(H) - Difference in elevation of water surfaces Nf - no. of flows Nd - no. of drops Pressure Head, delta(h) correct answers delta(h) = (delta(H))/(Nd) Pressure, P correct answers P = (Y)(h) Y = 9.81 (constant) h = [H-(Nd)(delta(h)] Area of Hydraulic Uplift Force (Trapezoid), Fa correct answers Fa = ((h)/(2))(B1+B2) Total stress, o correct answers o = o'+u o' - effective stress/pressure u - water pressure Effective stress, o' correct answers o' = o - u or (Y')(h) Water pressure, u correct answers u = Ywhw hw - height of water table Yw = 9.81 (constant) Buoyant Unit Weight, Y' correct answers Y' = Ysat - Yw Capillary Rise, hc correct answers hc = (c)/((e)(D10)) hc - height of capillary rise c - cohesion e - void ratio D10 - dia. @ 10% passing Factor of Safety (Heaving), Fs(heaving) correct answers Fs(heaving) = (o)/(u) Normally Consolidated, Sp correct answers Sp = ((Cc)(H))/((1+e))log((Po+delta(P))/(Po)) Po - effective soil pressure or (o') delta(P) - additional soil pressure caused by backfill H - height of consolidating Layer
