Method for generating bridge hole arrangement line and bridge pile from road design line based on CAD (Computer Aided Design)

The invention provides a method for generating a bridge hole arrangement line and a bridge pile from a road design line based on CAD, and the method comprises the specific steps: obtaining a target road design line based on AutoCAD, the target road design line being a polysemy line segment formed by connecting a straight line and/or a circular curve and an easement curve; reading a design parameter data information table of the hole arrangement line and the bridge piers, the design parameter data information table comprising bridge pier design parameter information of each pre-constructed bridge pier corresponding to the target road design line; calculating the construction hole distribution line of each pre-construction pier and the bridge pile construction coordinates of all the construction bridge piles corresponding to the pre-construction piers; and outputting the construction hole distribution line and the bridge pile construction coordinates. Bridge hole distribution lines and pier pile foundations can
