The invention discloses a full-parameterization establishing method for a road three-dimensional model. The road design process is taken as the start, and design parameters of cross and longitudinal sections of a road are taken as the input. Specific establishing steps include that a plane straight curve is stretched and expanded to form a longitudinal section, a road longitudinal section straight curve is established and folded to form a road center line, ultrahigh and widened cross sections are arranged at transition feature points to form road subgrade surfaces, side lines are extracted to be crossed with terrain, filling and digging segments are judged, filling and digging sections are automatically generated through an intersection point ray method, digging faces and slope filling faces are formed, the filling and digging operation is conducted, and the road three-dimensional model is generated. According to the full-parameterization establishing method for the road three-dimensional model, the defect that input parameters are undefined in significance in an existing design process is overcome, and the full-parameterization establishing method has the advantages that the fast response to design changes is achieved, road three-dimensional design calibration is achieved, earthwork calculation is achieved, road path planning comparison and selection are achieved, and virtual wandering is achieved.
