The lateral pressure in cohesion less soils is given by following formula:-
Following terms are used in the formula given below
Y=unit weight of soil, lb/ft3 or kg/m3
P=total thrust of soil, lb/linear ft (kg/m) of wall
H= total height of wall, ft (m)
KA= coefficient of active pressure
the cos i is not elaborated, is it the angle of friction of the soil?
define cos i.
