Soil Mechanics and Foundation A cylindrical specimen of saturated soil failed under an axial vertical stress of 100kN/m2 when it was laterally unconfmed. The failure plane was inclined to the horizontal plane at an angle of 45°. The values of cohesion and angle of internal friction for the soil are respectively 0.5 N/mm² and 30° 0.05 N/mm² and 0° 0.2 N/mm² and 0° 0.05 N/mm² and 45° 0.5 N/mm² and 30° 0.05 N/mm² and 0° 0.2 N/mm² and 0° 0.05 N/mm² and 45° ANSWER DOWNLOAD EXAMIANS APP
Soil Mechanics and Foundation A retaining wall 6m high supports a backfill with a surcharge angle of 10°. The back of the wall is inclined to the vertical at a positive batter angle of 5°.
