Abstract:In order to realize the fully assembled foundation of container modular building, the feasibility of the application in steel  screw piles foundation in this type of building was studied. The application status, calculation method of bearing capacity and anti-corrosion measures of steel screw piles foundation were summarized. The force and type selection of the steel screw piles foundation of the two-story container modular building under the seismic condition with the intensity of 8 degree（0.2g）, characteristic period Tg of 0.2,0.3,0.4,0.45,0.55,0.65s and the wind load condition with the wind pressure w0 of 0.5，0.6，0.7，0.8，0.9kPa respectively were studied. According to the mechanical characteristics of the steel screw piles foundation, the pre-stressed flexible tie rod was added to realize the integrity of the foundation overhead layer and enhance the overall stability of the steel screw piles，the standardized design of short column and all bolt connection structure used in this new kind of foundation can improve the processing efficiency and realize 100% building assembly.

Keywords:container modular building;steel screw piles foundation;connection structure
