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
