Facing up the fact that traditional earth pressure theory can not consider the effects of the displacement of retaining wall on earth pressure calculation
a new earth pressure calculating model considering the nonlinear effects of the displacement of retaining wall was set up
and influences and calculating ways of the parameters were studied. Centrifuge model tests showed that the calculating results of the model are coincident with the tests data. So the calculating model is credible
and it provides a new calculating way for earth pressure calculation.
