Engineering project rapid motion collision checking method

The invention relates to an engineering project rapid motion collision checking method. The method comprises the steps of adding motion behavior additional attributes to activity facilities and equipment in a design project; generating a virtual body for motion collision inspection; and performing static inspection on the virtual body, and obtaining an inspection result in combination with logic judgment. According to the invention, in BIM design, attributes such as the activity range, the motion constraint, the rotation characteristic, the combination constraint and the deformation characteristic are added to movable facilities and equipment, a BIM design program can automatically generate key site virtual bodies, static collision check is conducted on the virtual bodies, and then the result of motion collision check can be obtained; according to the method, motion simulation is not needed, so that the inspection speed is extremely high, and background real-time inspection can be realized in the design proce
