Design Length of Retaining Wall L = 2.80 m
Surcharge of earth h = 1.00 m
Unit weight of backfill Wb = 1.80 t/m3
Unit weight of Earth Ws = 1.90 t/m3
Unit weight of Earth Ws = 1.90 t/m3
Angle of internal friction of the earth fill ' = 20.0
Strength reduction factor for Soil property KR
= 0.7
Design value of Internal friction angle = tan-1 ( KR tan ' ) = 14.3 = 14.3
Design angle of friction between the wall and the soil
