Abstract: This paper presents the research results of the rigid retaining wall displacement on the magnitude of earth pressures on the wall. Under the laboratory model testing conditions, the value of earth pressures are measured with different rotational displacement around the bottom of the model wall. The earth pressure contour lines are plotted. The relationship between the earth pressure and the wall rotational displacement is compared.
