     determination of static and especially seismic bearing capacity of foundation using slip lines method is one the interested method in geotechnics project because of its simplicity. in slip lines method, the stress equilibrium equations on the characteristic lines are solved using the finite difference method. in this research, to determine the static and seismic bearing capacity of foundation two programs were codded in matlab. for seismic analysis horizontal and vertical seismic coefficient were inserted in equilibrium equations. comparison of the results shows that the proposed model can predicts close bearing capacity with respect to the literature. the results of sensitivity analysis show that the horizontal seismic coefficient and internal friction angle are the most effective parameters on bearing capacity of the strip foundation. the results indicate that earthquakes have a negative effect on the bearing capacity, so increase in the horizontal coefficient of the earthquake decrease the bearing capacity of the strip foundation significantly.
