A basic solution for ground settlement caused by horizontal movement of retaining wall is derived. And then a simplified method is proposed for computing the ground settlement caused by arbitrary mode of movement of wall based on the basic solution. The FEM numerical solution is then used to verify proposed simplified method by comparison of their solutions to ground settlement

which is caused by three modes of horizontal rigid movement for translation

rotation about bottom and rotation about top

respectively. Finally

the simplified solution is applied to prediction of measured data in the field. The predicted settlement curve of ground is similar to the measured one; and the location of the maximum settlement is close to the measured one as well

showing that the simplified analytical method is practicable.
