Foundation bearing capacity is one of the most important research topics in the field of geotechnical engineering. Focusing on circular shallow foundation, and starting from spatial problem, and according to the theory of limit analysis, a more reasonable upper bound solution for the ultimate bearing capacity of the three-dimensional circular shallow foundation is presented theoretically. This thesis chooses a suitable foundation failure mode and motor displacement velocity field, and firstly considers the influence of the lateral soil pressure on the limit bearing capacity of circular shallow foundation and the effects of soil weight under the base of the foundation and surcharge load. Combined with the project, the upper bound solutions are calculated using corresponding Matlab program and compared with the serve value in other techniques. The upper bound solution is proved to be more rational and practical.
