Method for optimizing elevation marking of retaining wall elevation

The invention discloses a method for optimizing elevation labeling of a retaining wall facade map, and the method comprises the following steps: establishing a selection set for elevation character 'block' units in elevation labeling in a retaining wall facade AutoCAD map exported by drawing software; after attribute judgment, overlapping judgment and related data extraction of the 'block' units, calculating and determining a distance disw required to be moved by an overlapping part, and according to a calculation result, automatically moving and adjusting the overlapped character annotations. According to the method, the operation convenience is high, overlapped elevation characters or similar primitives such as size marks, stake marks and coordinates can be recognized, automatically judged, deleted and adjusted, elevation mark optimization of the retaining wall vertical view is achieved, manual adjustment is not needed, the workload of designers is effectively relieved, and the drawing efficiency and accura
