Abstract :

For the conventional retaining wall in a kind of gravity wall, the weight of the structure influences the stability of the retaining wall. Moreover, the weight of the retaining wall is determined by its dimension. The assumptions of retaining wall dimension are determined by trial and error. If the retaining wall is not enough to bear the load, the dimension of the retaining wall must be changed. In this study, we analyze a gravity retaining wall according to Rankine’s theory. The active earth pressure and passive earth pressure have been calculated using Rankine’s theory and the stability of the retaining wall against sliding, overturning, and bearing capacity is also calculated. Finally, the stability is compared through discrete element modeling simulation. As a limitation of this study, there is only one layer of backfill material considered due to simplicity. Given the hypothetical computation and DEM simulation results, the gravity retaining wall shows slight sliding and overturning failure. There is no bearing capacity failure for this structure. As there are no micro-cracks found in the simulation, it justified the theoretical calculations.
