General curve element acquisition method for road curve

The invention discloses a general curve element acquisition method for a road curve, and relates to the field of engineering design and construction, and the method comprises the steps: S1, building an engineering coordinate system in a design stage, and determining a target road curve and basic data thereof; s2, according to the basic data of the target road curve, obtaining a curve corner of the target road curve and curve parameters of an easement curve segment; s3, establishing a temporary coordinate system, and acquiring coordinates of related curve control points and auxiliary points of the target road curve in the temporary coordinate system; and S4, obtaining curve elements of the target road curve. According to the universal curve element obtaining method, the complex process of obtaining curve elements through the inner displacement distance p and the tangent vertical distance m in the prior art is omitted, the steps are omitted and simplified, a multi-curve combined line which is difficult to desig
