Abstract：Based on the load structure mode of Rankine soil pressure theory and continuum mode，the safety of subway deep shaft retaining structure was analyzed to investigate the applicability of Rankine soil pressure theory used for design calculations of the deep shaft retaining structure which commonly used in metro design. On this basis，considering the different stratum conditions，type of support，excavation sizes and other factors，this paper simulated the various conditions of deep shafts in three-dimension numerical simulation by means of FLAC3D finite difference calculation software to understand the soil pressure of deep shaft and deformation law. In addition，the coefficient of soil pressure and functional relationship among soil pressure，deformation of support structure and depth were proposed. Furthermore，in-site monitoring soil pressure of concrete subway shaft was carried out to confirm the applicability and reasonableness of the mentioned soil pressure for calculation. The research results can provide a reference for the design of subway deep shaft.
