ABSTRACT
Case 3: Cantilever Wall with Sand Backfill and Water Table Above Dredge Line [Fig. 20.12] The various expressions for this case may be developed as in the earlier cases. The various relationships may be written as
PI = rh IKA Pa = yhjKA + Yb h2 KA = (yh j + Ybh2) KA P = 2Qu-yH p/ = 2Qu + (yh j + Ybh2)
1 - Pa = 2" ( PI H + Pah2)
The expression for the second degree equation in D is
CI D2 + C2 D + C3 = 0
where
CI = [2Qu-(yhj+Ybh2)] C2 = -2Pa
