Engineers often overlook the difference between "at-rest" earth pressure ( Kocap K sub o ) and "active" earth pressure ( Kacap K sub a
Calculate the factor of safety against uplift. If the weight of the culvert plus the soil above it doesn't exceed the upward buoyant force by at least 1.2 to 1.5, you must increase the thickness of the bottom slab or add "toe" extensions to catch more soil weight. 2.
