| Abstract: | Based on the theory and test results of reinforced foundation,an upper bound failure mode is proposed. The limit analysis method is used to deduce the bearing capacity of reinforced foundation. It is shown that the calculated upper bound solution of the ultimate bearing capacity is in reasonable and agreement with the results of other methods. |
