The invention discloses a BIM-based fabricated
subway station design and construction method, and relates to the technical field of design and construction, and the method comprises the steps: constructing a soil layer
data set and an underground
water level data set, and importing BIM
software to create a three-dimensional
station structure model; using a BIM model to simulate the load of the
subway station in a static state, calculating the first bearing strength of each fabricated building component of the
subway station, marking static dangerous components, and calculating the static bearing evaluation index of the whole subway
station; after no static dangerous component exists, using a BIM model to simulate the dynamic load of the subway
station, calculating the second bearing strength of each fabricated building component of the subway station, and calculating the dynamic bearing evaluation index of the whole subway station; after no dynamic dangerous component exists, the comprehensive bearing strength of the whole subway station is calculated, and design optimization is conducted on the whole subway station till the comprehensive bearing strength of the whole subway station does not exceed the comprehensive bearing strength threshold value. And the
structural safety of the subway station under various working conditions can be ensured.
