THE LEAST UPPER-BOUND SOLUTIONS FOR BEARING CAPACITY FACTOR N_y

摘要

The correct solution to bearing capacity factor N_y due to soil self-weight is not available by the classical theory of plasticity, so numerical approximation based on limit equilibrium method or limit analysis is required. Limit analysis using upper-bound theorem can giver an upper-bound solution for the bearing capacity problem. If the critical failure mechanism is found, such an upper-bound solution is a good approximation for the correct one.
