Study on the Calculation Method of Earth Pressure on Retaining Wall in the Mode of Translation

Focusing on rigid retaining wall under translation movement mode, the earth pressure under non-limit state considering translational movement effect is studied. Considering the translational displacement effect of internal friction angle of the backfill and the wall soil friction angle,we established the relation formula between internal and external friction angle and displacement and got strength and distribution of horizontal earth pressure, strength and the acting point of resultant force on retaining walls at any displacement in mode of translation. We also compare the calculation of earth pressure obtained by the calculation method proposed in this paper with the measured values of the model and found and they are on the whole the same.
