Abstract: The traditional ultimate bearing capacity formula is verified through numerical analysis in this essay. It is shown that the contribution of base width to ultimate bearing capacity in traditional formula is correct. Through the numerical analysis, aiming at the contribution of base width limitation to foundation bearing capacity in code method, we studied a reasonable method for ascertain the bearing capacity, and we believe that determining the bearing capacity of soil with settlement and safety factor of the real foundation is more reasonable. The reflection of the bearing capacity of soil from base width has already effect the settlement and safety factor, therefore we can receive the bearing capacity of soil more reasonable with no necessary to limit the base width.

Key words: foundation width, bearing capacity of soil, Terzaghi's formulas of bearing capacity, numerical analysis
