AbstractBased on the actual engineeringthe common pile-foundation types and the bearing capacity calculation method of bridges in karst area were summarized. Meanwhile, a computing research on the safe thickness and the socket depth of the socket pile bearing stratum was conducted to provide some references for the design of bridge foundation in karst area.
