Stability computations in the Geotechnics with the Kinematic
Element Analysis Method (KEA)

The conventional stability proofs in geotechnics (earth
pressure determination according to DIN 4085, embankment
stability, ground failure, sliding circle according to DIN
4084, shear failure according to DIN 4017 etc..) depending upon
situation indicate often too small or too large safety against
stability because of insufficient accuracy of the failure
figure. This is already the case, if concentrated loads,
geometrical constraints, lubrication lay-ers or the like cause
the formation of sliding surfaces, which cannot be represented
by the simplified failure mechanisms as suggested by the
standards. With the help of the Kinematic Element Analysis
(KEA) arbitrary failure mechanisms can be modelled and
optimized and thus most geometrical situations can be modelled
correctly.
