Through the survey of Guangzhou subway deep foundation pit design documents, some problems about calculation in the design of subway foundation pit are discussed, including comparison between classical method and elastic method when using elastic foundation beam calculation method, total method and incremental method, water and soil calculating separately and combined method and so on, also to analyze current common constitutive models used in soil and retaining structure coordinately working finite element method analysis. Some foundation pit calculation examples are elaborated, calculation results is analyzed, and the advantages and disadvantages of various calculation methods is compared, which can provide a reference for metro pit design and calculation.
