Most conventional calculations of static and seismic active earth pressures are based on a linear mohr-coulomb MC failure criterion . In recent years many efforts have been focused on stability problems of geotechnical structures with the limit analysis method. the limit analysis mehtod includes the upper and lower bound theorems. by using the two theorems the range in which the true solution falls can be found this range can be narrowed fiding the highest possible lower bound solution and the lowest possible upeer bound soloution . the solutions obtained from the limit analysis method are rigorous in that no assumption regarding forces is required. in this paper a limit analysis method with a MC linear yield criterion in the framework of upper bound theorem of plasticity for calculating both static and seismic active earth pressures is presented.
