Question

Quizplus · Accepted Answer

The four basic modes of geotechnical instability of an earth retaining structure are: sliding, overturning, bearing capacity and global stability. These modes may not be applicable to all wall types. Depending on the wall type and the load support mechanism used, there may be additional internal instability modes encountered: pullout, tension breakage, bending, or shear.
