Abstract

The invention discloses a BIM-based bridge conical slope three-dimensional modeling method, system and device and a storage medium. The method comprises the following steps: obtaining a conical slopebottom surface oblique elliptic equation; according to the coordinate points on the oblique ellipse, solving a B spline curve equation of the oblique ellipse on the bottom surface of the conical slope, wherein a B spline is used as a lofting path of the bottom surface of the conical slope; determining a lofting object according to the height of the conical slope, the central point of the oblique ellipse and the coordinate point on the oblique ellipse, and sweeping according to the lofting object and the lofting path to obtain a conical slope three-dimensional model; obtaining a conical slope position according to the abutment position information; matching the conical slope three-dimensional model to a corresponding conical slope position. The method at least has the advantages that three-dimensional modeling of the conical slope is achieved, three-dimensional visualization of the conical slope is achieved, volume calculation of the conical slope is facilitated, and the calculation result is high in accuracy.

Description

technical field [0001] The present invention relates to a bridge three-dimensional modeling technology, in particular to a BIM-based three-dimensional modeling method, system, equipment and storage medium for a bridge cone slope. Background technique [0002] The conical slope refers to the conical slope protection built at the junction of the bridge culvert and the roadbed in order to protect the embankment slope from erosion. Also known as cone slope protection, when the buried, pile, column abutment or abutment layout cannot completely retain the soil, in order to protect the stability of the embankment at the bridge head and prevent erosion, cone slopes should be set on both sides. The slope in the direction of the bridge should be consistent with the slope of the embankment, and the slope in the direction of the bridge should be determined according to the height, soil conditions, flooding conditions and paving or not. Because the cone slope is a three-dimensional spec...
