Lecture 28 : Anchored sheet pile walls [ Section 28.5 : Moment reduction for anchored wall ]
Moment reduction factor for cohesive foundation soils. Moment reduction factors for piles in homogeneous cohesive soils also depend on the stability number ( ) given by
where, c = cohesive strength of the soil,
= effective vertical soil pressure on the retained side of the wall at the elevation of the dredge line .The curves for are given for various combinations of system parameters in Figure
