1-sin according to jacky.
0.9(1-sin) according to Fraser.

Earth Pressure at Rest Ko = 1 - Sinθ.
Active Earth pressure Ka = tan2 (45 - φ/2).
Passive Earth Pressure Kp = tan2 (45 + φ/2).

Here, k= 1- sinθ.

Basudeb said:   8 years ago
At rest condition, k=1-sin (θ).

Earth pressure for normally consolidated soil at rest is K = 1-Sin(theta). So answer is right.

Earth pressure of soil at rest is Ko = 1-SIN (φ). Mann your answer is given in the option but answer is none of these.

The earth pressure of a soil at rest, is proportional to tan^2(45°-φ/2).
