Abstract: Based on the characters of ground failure under eccentric loads, the discontinuous stress fields and discontinuous velocity fields are constructed. The characters of discontinuous lines of stress and velocity are analyzed. By upper and lower bound theorems, the model of calculation and the method for bearing capacity are given. The stress fields and the corresponding mobile fields are obtained by the numerical calculation to solve three kinds of boundary value problems. The stress fields satisfied with all velocity boundaries are found. The rigorous solution of bearing capacity under eccentric loads is solved. The computation results show that the method proposed to solve the limit equilibrium problem is available.

Key words: limit analysis, bearing capacity, slip line, upper and lower bound theorems
