SEISMIC DESIGN OF REINFORCED EARTH RETAINING WALLS AND BRIDGE ABUTMENTS

It is generally agreed that the stability of retaining walls exposed to earthquakes is not
a matter for real concern.
In a paper delivered in 1970 at the ASCE Specialty Conference, Professors H. Bolton
Seed and Robert V. Whitman said:
"Few cases of retaining wall movement or collapse
of walls located above the water table have been
reported in the literature on earthquake damage.
(...) it seems likely that the small number of
accounts of retaining wall performance is not
necessarily indicative of the lack of occurrence of
wall movements: this type of damage is not
particularly dramatic compared with other forms of
earthquake damage and thus may often be
considered of minor significance."
