Determine the active and passive force acting on a 3 meter high wall that supports clay with an undrained shear strength of 100 kPa and a unit weight of 19.20 kN/m


Expert Answer

Step 1

Given information

The height of wall (H) is 3 m.

The undrained shear strength of clay qu is 100 kPa.

The unit weight of soil (γ) is 19.20 kN/m.

Step 2

The relationship between cohesion and undrained shear strength of clay is given by,
