Abstract Research purposes ：The foundation bearing capacity is a fundamental issue in design of foundation，but the current standards are different in design theories and design parameters, and there are lots of the different technical terms in different times and in different industries. In order to provide the basis for the limit state design method for the foundation treatment, the basic design concepts, design theories and design methods for determination of the bearing capacity of the foundations of building, harbour, highway and railway were summarized.
Research conclusions ： ( 1 ) At present, the safety factor method is mainly used in the architecture and railway industries. The limit state design method is used for the harbour foundation and with this method，the reliability of strength index, the safety of the structure and the situation of the soil are comprehensively considered in the partial factors of the resisting force of the foundation. (2) Due to the particularity of the geotechnical engineering，the limit state method used for geotechnical engineering should be understood correctly，the previous statistical analysis and experiences should be focused on，the survey method and design parameter should be normalized and the conceptual design and the site monitoring should be emphasized. (3)The result can direct the research on the reinforcement of railway foundation with the limit state design method.
