Numerical Analysis of Ultimate Bearing Capacity of Embedded Foundation
Soil is divided for finding the ultimate bearing capacity of foundation with given buried depth and size. Supposing a uniform load acts on the foundation, Mindlin’s integral formula and corner points method are used to get extra stress of every mesh knot by MATLAB program, then the principal stress is found. Combining with failure criterion, MATLAB program is used to find coordinates of points which are destroyed. Using graphic processing function of MATLAB, the failure points are showed in the coordinate. Increasing the rectangular uniform load, the failure points are found until these points can form a continuous failure surface. This rectangular load is the ultimate bearing capacity of the foundation. The method can avoid errors brought by unreasonable hypotheses of the empirical formulas; and the three-dimensional failure surface of the foundation soil is obtained.
