Abstract Research purposes:Retaining structure belongs to the geotechnical engineering structure, the limit state classification of geotechnical engineering is more difficult than the structure projects. Based on the limit state concept at home and abroad, this paper makes a comparison and analysis of the common and difference of geotechnical engineering and structural engineering limit state, teases the retaining structure limit state and focuses on limit state of open-cut foundation and pile foundation, proposes the recommendation of limit state classification of retaining structure.Research conclusions:(1) The generalized limit state can be considered as a function which can achieve the expected requirements, the limit state is not limited to the concept of damage and failure, and its extension has been expanded to the requirements of that the goal of expected design cannot be achieved——a prescribed limit. (2) Retaining structure belongs to the category of geotechnical engineering, its limit state includes structure overall stability limit states and the structural stability limit state which includes the bearing capacity limit state and serviceability limit state and limit state between them, the state needs to be studied further. (3) In general area, the compressive stress limit state of open-cut foundation and lateral pressure limit state of rock foundation anchor pile foundation can be considered as the serviceability limit state. (4) The research conclusion is useful for guiding the design research of retaining structure limit state.
