Three-dimensional design method and system for roadbed slope protection engineering

The invention relates to the field of geotechnical engineering design, in particular to a three-dimensional design method and system for roadbed slope protection engineering. The method comprises the following steps: acquiring slope basic data; according to the slope basic data, section points on the cross section at each mileage are calculated, the section points comprise a slope section starting point and a slope section ending point, and the section points at a plurality of mileages form a point set; constructing a grid surface according to the point set; establishing a corresponding relation between a three-dimensional space position relation of each grid in the grid surface and the slope protection parameters; according to the corresponding relation, a protection model corresponding to the slope protection parameters is imported into a three-dimensional space corresponding to the grid face, and a slope protection three-dimensional model is generated. Due to the fact that the points are directly drawn on
