Much experimental work has not been so far done to study the effect of the wall movement on earth pressure in cohesive soils in general let alone in soft cohesive soils. On the other hand, a lot of experimental works have been conducted on sand. The attempt on all the model tests on sand was to develope a mobilization function of the passive resistance dependent on the wall displacement. The paper presents an attempt to develop a soil stiffness dependent mobilization function of the earth resistance of normally consolidated soft soils numerically using the FEM. Three types of the wall movement had been investigated. These are: parallel translation, rotation of the wall about the head and the toe.
