Question

The lateral earth pressure coefficient of a soil, $K_a$ for active state, $K_p$ for passive state and $K_0$ for at-rest condition, compare as

• A. $K_0<K_a<K_p$
• B. $K_a<K_0<K_p$
• C. $K_a<K_p<K_0$
• D. $K_p<K_0<K_a$

Answer 1

The correct option is B $K_a<K_0<K_p$

$K_a=\frac{1-\sin \varphi }{1+\sin \varphi },K_p=\frac{1+\sin \varphi }{1-\sin \varphi }\text{and}{K}_o=1-\sin \varphi K_p>K_o>K_a$
