Question

Given that for a soil deposit,
$K_{o} =$ earth pressure coefficient at rest
$K_{a} =$ active earth pressure coefficient
$K_{p} =$ passive earth pressure coefficient
$μ =$ Poisson's ratio.

Solution

The correct option is D $1 / K_{o}$
$K_{o} = \frac{μ}{1 - μ} \Rightarrow \frac{1}{K_{o}} = \frac{1 - μ}{μ}$
