The active earth pressure of a soil is proportional to (where φ is the angle of friction of the soil)
The active earth pressure of a soil is proportional to (where φ is the angle of friction of the soil)
where Pp is the passive earth pressure, γ is the unit weight of the soil, H is the height of the soil mass, and Kp is the passive earth pressure coefficient. Therefore, we can see that the passive earth pressure is proportional to cot2[45°-φ/2].
