judging whether the simulation calculation analysis result meets mechanical and economic indexes, and if so, carrying out detailed design on the construction drawing; if not, the parameters in the solid finite element model are adjusted and the mechanical model is updated, and step S9 is executed again.
9. The BIM-based large-span through-put type beam-arch combined rigid frame bridge three-dimensional forward design method according to claim 1, characterized in that: the three-dimensional checking comprises integrity checking, normalization checking, rationality checking, drawing die consistency checking, collision checking and coordination checking.
10. The BIM-based large-span through-put type beam-arch combined rigid frame bridge three-dimensional forward design method according to claim 4, characterized in that: the step S10 specifically includes:
carrying out three-dimensional checking on the design result after detailed design to obtain a three-dimensional checking result;
judging whether the three-dimensional checking result meets the three-dimensional checking requirement, if so, entering the step S11; if not, modifying the parameter information in the parameterized design model to realize the modification of the construction drawing model, the calculation quantity model and the calculation model, and returning to execute the step S9.
