C ONCLUSION By understanding all factors, which effected to the soil, could be starting way of the improvement of any soil. Some element have linear and some of them nonlinear effect on soil bearing capacity. Unit weight has linear correlation with bearing capacity at any degree of angle of friction, cohesive of soil and width and depth of foundation have nonlinear correlation with bearing capacity at any angle of friction. Data has been produces in this paper could make clear economical design of any foundation. Increasing of bearing capacity in a soil with low angle of friction is not same, as a soil with high level of angle of friction, at any of them should apply proper technique. R EFERENCES [1] V. K.
