Active Earth Pressure: The lateral stress generated by soil when it attains a state close to failure, typically induced by a movement away from a retaining structure.

Selected topics in soil response and technology needed in conventional geotechnical analysis and design; shearing behavior in clays; subsurface investigation; lateral earth pressures, retaining walls, ...

Retaining walls ... adequate retaining wall drainage, moisture builds up in the earth behind it. As that soil soaks up water, it gains considerable weight and pushes with tremendous force—what ...
